Feat: add eslint command for generated test file

[BaseInfinity]

This helps to ensure that the test file is formatted correctly for given project instead of trying to figure out formatting code myself.

I think it will be cleaner here to use eslint class instead of shelling out to call it on command line. It also gives you more control and separates it from the project’s eslint configuration.

see here: https://eslint.org/docs/latest/integrate/nodejs-api#eslint-class

Oh I like that solution instead! Thanks for the link I'll look into it

I'll most likely be able to get to this in the next couple weeks, I plan to make the suggested changes =)

I've been busy sorry, I don't plan to dive into this again for another month or so
