Modernizing the codebase

[shilangyu]

This package uses old dependencies making it hard to use in modern projects. Most notably, cool_linter uses analyzer v2 while the current version is v5. This issue is about bumping all dependencies to their newest constraints and releasing a new version.

I am willing to send such a PR, but I need assurance that something like that will be accepted so my work doesn't go to waste. I plan to bump all deps and set dart sdk version to 3.0. @jWinterDay what do you think?

@shilangyu hello! great idea

[shilangyu]

@enikiforov-carito are you a maintainer/person with push rights?

[jWinterDay]

@shilangyu sure. It was another account :)

I gave it a shot, but after migrating the easy stuff I was left with some bigger breaking changes which I do not know how to correctly migrate to new analyzer version. In the meantime I have started using custom_lint and found it easy to use to replace my need for cool_linter. I can push my progress that I made with migrating cool_linter if that would be of use?

@shilangyu hello. of course, push it. If I find free time I will see

Pushed everything to my fork's branch. Feel free to duplicate this branch if needed. master...shilangyu:cool_linter:task/modernize

What is left to migrate is the file src/lib/plugin.dart.
