We appreciate you spending the time to work on these changes. Please
provide enough information so that others can review your pull request.
The three fields below are mandatory.

Before submitting a pull request, please make sure the following is
done:

1. Fork [the repository](https://github.com/facebook/react) and create
your branch from `main`.
  2. Run `yarn` in the repository root.
3. If you've fixed a bug or added code that should be tested, add tests!
4. Ensure the test suite passes (`yarn test`). Tip: `yarn test --watch
TestName` is helpful in development.
5. Run `yarn test --prod` to test in the production environment. It
supports the same options as `yarn test`.
6. If you need a debugger, run `yarn test --debug --watch TestName`,
open `chrome://inspect`, and press "Inspect".
7. Format your code with
[prettier](https://github.com/prettier/prettier) (`yarn prettier`).
8. Make sure your code lints (`yarn lint`). Tip: `yarn linc` to only

## Summary

<!--
Explain the **motivation** for making this change. What existing problem
does the pull request solve?
-->

Adds changelog entries for the last two minor releases of
`eslint-plugin-react-hooks`. Fixes #31717.

I chose to not include #31208 (8382581)
and #32115 (fd2d279) in the changelog
as they only changed internals that do not affect consumers of the
plugin, and it doesn't seem like the changelog previously included such
changes.

Changes are sorted by importance (rather than by commit date), with the
most important changes first.

## How did you test this change?

<!--
Demonstrate the code is solid. Example: The exact commands you ran and
their output, screenshots / videos if the pull request changes the user
interface.
How exactly did you verify that your PR solves the issue you wanted to
solve?
  If you leave this empty, your PR will very likely be closed.
-->

Docs only, nothing to test.
