chore: brought in typescript-eslint@v8 with stylistic preset (#10911)

This applies two internal tooling updates:

* Bumps typescript-eslint to its beta v8:
https://typescript-eslint.io/blog/announcing-typescript-eslint-v8-beta
* Enables typescript-eslint's [shared `stylistic`
config](https://typescript-eslint.io/users/configs#stylistic) for
internal code (not `eslint-config`)

Any changes (will be) commented inline. This also doesn't tackle three
good followups:

* Rules with many existing reports I kept disabled under a `TODO:`
comment in `.eslintrc.js`
* A reasonable next step for the project would be to look through those
and decide which should be fixed up.
* This doesn't enable [typed
linting](https://typescript-eslint.io/getting-started/typed-linting)
internally
  * Would definitely recommend next!
* Onboarding to ESLint's flat config
  * Blocked on #10897 

**There should be no user-facing functional changes**. It should just be
cleanups.

⚠️ This isn't ready for merge, as it uses `rc-v8` versions of
`typescript-eslint`. Just posting as a reference prior to v8 going
stable.
* Once v8 is stable, I can update this to use the released version.
* Alternately, if you'd like these changes sooner, I can make a version
of this that doesn't update to `rc-v8` - it'll just have slightly fewer
changes...

This PR came out of a casual conversation with @Tobbe. I'm happy to file
an issue / make a more formal internal tooling request if you'd prefer.
❤️

+- chore: brought in typescript-eslint@v8 with stylistic preset (#10911) by @JoshuaKGoldberg
+
+This change updates Redwood linting config and introduces some changes to the linting rules that are applied to your project.
+
+Specifically:
+
+1. `jsx-a11y/no-noninteractive-element-to-interactive-role` has it's default config updated.
+3. `@typescript-eslint/explicit-function-return-type` used to be turned off, now it's no longer applied.
+4. `@typescript-eslint/no-empty-interface` - used to be turned off, now it's no longer applied.
+5. `@typescript-eslint/explicit-module-boundary-types` - used be turned off, now it's no longer applied.
+6. `@typescript-eslint/ban-types` - used to be 'warn', now it's no longer applied. This has been replaces with a set of smaller more specific rules.
+7. `no-empty-function` - used be turned off, now it's no longer applied. The ts-eslint flavour is still there and turned off still.
+8. `camelcase` - used to be turned off, now it's 'warn'.
+9. `@typescript-eslint/camelcase` - used to be turned off, now it's no longer applied.
+10. `no-use-before-define` - used to be turned off, now it's no longer applied.
+11. `@typescript-eslint/no-use-before-define` - used to be turned off, now it's no longer applied.
+12. `@typescript-eslint/prefer-namespace-keyword` - used to be turned off, now it's 'error'
+13. `unicode-bom` - used to be turned off, now it's no longer applied.
+14. `@typescript-eslint/adjacent-overload-signatures` - used to be 'error', now it's no longer applied.
+15. `@typescript-eslint/no-explicit-any` - used be 'warn', now 'error'
+16. `@typescript-eslint/no-inferrable-types` - used to be 'error', now it's no longer applied.
+17. `no-loss-of-precision` - used be 'off', now 'error'
+18. `@typescript-eslint/no-loss-of-precision` - used be 'error', now it's no longer applied.
+19. `@typescript-eslint/no-non-null-assertion` - used be 'warn', now it's no longer applied.
+20. `valid-typeof` - used be either 'error' or 'off', now always 'error'
+21. `no-unused-expressions` - used be always 'error', now either 'error' or 'off'
+22. `@typescript-eslint/prefer-function-type` - newly added as 'off'
+23. `@typescript-eslint/no-require-imports` - newly added as 'off'
+24. `@typescript-eslint/no-empty-object-type` - newly added as 'off'
+25. `unicorn/template-indent` - newly added as 'off'
+26. `@typescript-eslint/no-duplicate-enum-values` - newly added as 'error'
+27. `@typescript-eslint/no-unsafe-declaration-merging` - newly added as 'error'
+28. `@typescript-eslint/no-unsafe-function-type` - newly added as 'error'
+29. `@typescript-eslint/no-unused-expressions` - newly added as 'error'
+30. `@typescript-eslint/no-wrapper-object-types` - newly added as 'error'
+31. `no-new-native-nonconstructor` - newly added as 'off'
