Use typescript-eslint instead of TSLint

[JoshuaKGoldberg]

This repository still uses TSLint, which is being deprecated: palantir/tslint#4534. It'd be great to move it over to typescript-eslint to no longer use deprecated packages.

Protip: tslint-to-eslint-config is the recommended package to do so!

Will this be work of removing TSLint from package.json and adding new linter typescript-eslint, and migrating tslint configurations?

[JoshuaKGoldberg]

That's correct @anshulxyz!

Sounds like a good-first-issue, I'll let some newcomers get this 🙏

Hi, I am sorry, but i am unable to do this. My schedule changed.

Not a problem, thanks for the interest! I'll hide these posts so other folks aren't deterred.
