🐛 Bug: eslint does not report problems on `tasks.json` in VS Code

Bug Report Checklist

• I have tried restarting my IDE and the issue persists.
• I have pulled the latest main branch of the repository.
• I have searched for related issues and found none that matched my issue.

Expected

I created a new repo yesterday using create-typescript-app using the "everything" setting (woo!). I set up a few tasks in VS Code's tasks.json and pushed a PR, at which point I noticed that I was getting some eslint errors because of unsorted keys in my tasks.json.

These were reported via GitHub Actions CI and when I run pnpm lint, but they were not reported in VS Code like lint errors in .ts files are.

Actual

I would expect eslint issues in tasks.json to be reported in VS Code (so that I can quick fix them!).

Additional Info

I noticed that "json" is in the eslint.probe list in .code/settings.json, but maybe it also needs to be told about JSON files some other place?

Here's the PR and repo: danvk/gravlax#3

Hmm, looks like using eslint.probe for jsonc files isn't yet supported in vscode-eslint: microsoft/vscode-eslint#1786. Marking as blocked pending discussion there.

Worst case scenario, we can go back to eslint.validate. But that's described as old and legacy so I'd rather not for a bit.

Good news, looks like this was resolved by microsoft/vscode-eslint#1787! I tried out a straightforward rule violation locally by adding a trailing comma in .vscode/tasks.json and it worked:

$ npx eslint .vscode/tasks.json

/Users/josh/repos/create-typescript-app/.vscode/tasks.json
  7:17  error  Unexpected trailing comma  jsonc/comma-dangle

✖ 1 problem (1 error, 0 warnings)
  1 error and 0 warnings potentially fixable with the `--fix` option.

🚀.
