eslint does not support TypeScript 5

[JasonWeill]

Since upgrading to TypeScript 5 RC (#13872), running jlpm lint (which in turn runs jlpm eslint) produces a warning:

=============

WARNING: You are currently running a version of TypeScript which is not officially supported by @typescript-eslint/typescript-estree.

You may find that it works just fine, or you may not.

SUPPORTED TYPESCRIPT VERSIONS: >=3.3.1 <4.8.0

YOUR TYPESCRIPT VERSION: 5.0.1-rc

Please only submit bug reports when using the officially supported version.

=============

eslint continues to run, but this warning repeats every time jlpm lint runs.
