I have another question
After executing yarn&&yarn lint

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

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 <4.9.0

YOUR TYPESCRIPT VERSION: 4.9.3

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

=============
{
"@typescript-eslint/eslint-plugin": "^5.42.0",
"@typescript-eslint/parser": "^5.42.0",
}
I checked https://github.com/typescript-eslint/typescript-eslint/tree/v5.42.0
The version range of TypeScript currently supported by this parser is >=3.3.1 <4.9.0

typescript in package

{ "typescript": "^4.9.3", }
Do i need to upgrade the typescript eslnt version number to a matching typescript version in another pr

No, all good. That's just a warning because our TS version is a bit too new.
