Description

This just replaces micromatch dependency with the picomatch package. picomatch is part of micromatch and the pluginutils-plugin only uses the matcher function which is the same as using picomatch directly (See https://github.com/micromatch/micromatch/blob/master/index.js#L104).
This reduces dependency size.

Also added custom types until picomatch adds types on it's own. (See micromatch/picomatch#53 (comment))

Thanks for suggesting this. The one big hangup for me right now is that I don't want plugins to be in the business of maintaining types for dependencies. That's ripe for technical debt. If the picomatch folks don't respond over the next few days, I would suggest adding those types to https://github.com/DefinitelyTyped/DefinitelyTyped/. If they get published there or in picomatch itself, then I'm all about merging this.

Alright, I understand that. I'll add the types to DefinitelyTyped if they don't respond.

@Patcher56 We're still open to this change. Any word on the types situation?

[p-kuen]

Unfortunately no comment on the picomatch pull request. I am very busy at work rn, but will add the types to DefinitelyTyped on weekend. After that we can we remove the type declarations from this PR.

Is this ok for you?

Edit: Just opened a PR to DefinitelyTyped. DefinitelyTyped/DefinitelyTyped#44221

[p-kuen]

I just replaced the picomatch.d.ts file with the newly created @types/picomatch package.

Thanks! I'll take care of that lock file mismatch for you a little later today (that's my plan anyhow) and we'll merge this.
