Overview

This adds support for Typescript 5.4, which was recently released as generally available - https://devblogs.microsoft.com/typescript/announcing-typescript-5-4/

As per the issue #8314 - we will need to regenerate the lib.d.ts types.

There is also more to do than just those numbers.
Feel free to action it - here is the guide:
https://typescript-eslint.io/maintenance/pull-requests/dependency-version-upgrades#adding-support-for-a-new-typescript-version

Start at step 4

Thanks @bradzacher !

I looked at step 4, but it's only about updating an RC version of Typescript, which isn't the case here - this is the GA version, so I skipped to step 6.

I updated the types and then updated the doc as well, it was asking to change devDependencies when the typescript version is actually in resolutions now.

Let me know if there's anything else to do to get TS 5.4 supported, thanks!

[bradzacher]

LGTM - thanks for doing this!
