Add Minitest 6 Support

[rmm5t]

What does it do?

• Remove --guard flag for minitest 6 support
• Limit minitest to v5 or v6
  Removes support for minintest v3 and v4 and requires ruby >= 3.2
• Remove legacy old_runner for minitest < 5
• Regen rubocop_todo.yml

What else do you need to know?

• Afterwards, the goal of this PR is to lead in a new 3.0.0 release of guard-minitest.

@thibaudgg @rymai What's the appetite for more help here to get guard-minitest up and running with Minitest 6?

In addition to this PR, it looks like the CI suite could use some help both porting to github actions and also modernizing the build matrix. I'm happy to help if we can get more eyes on this gem.

Hey @rmm5t,

For full discloser, I haven't used guard and guard-minitest for quite a while now, so I'm a bit out of the loop. But please go ahead, I think it makes sense to first give the tests suite and CI a bit of love (even rewrite it all with minitest instead of RSpec) and then support minitest 6 (this PR). What do you think?

One concern would be backward compatibility, if those changes aren't compatible with minitest 5 then we should do a major gem version release.

[rmm5t]

@thibaudgg With #165 merged and a planned 2.x release of guard-minitest ahead of merging this PR, I think this PR is now lined up well to prepare for a later 3.x release. That way, we maintain backwards compatibility in 2.x while being able to look forward with 3.x releases.

Friendly nudge here...mainly because I'll have time available this week to get guard-minitest versions up to snuff, and I have several projects that can benefit from minitest 6 and working guard workflows.

#165 (comment)

If willing to add me to rubygems and as a collaborator here, I'm happy to get a release version out (likely v2.4.7 or v2.5.0) that limits this gem to minitest <=5 for better bundler dependency management.

My handle on rubygems is the same as github (rmm5t).

Then, I can follow-up with cleaning up #164 and prepping for a v3.0.0 of guard-minitest that is limited to minitest >=5, <7.

Looks good to me, I'm also up for adding @rmm5t as collaborator on this repo and on rubygems. @rymai does that sound good to you?

[rymai]

Sounds good to me, thanks @rmm5t! ❤️

[rmm5t]

Thanks @thibaudgg & @rymai!

I just pushed a few logistics commits to master in prep for a v2.5.0 release.

However, could I also please get access to rubygems?

You do not have permission to push to this gem. 
Ask an owner to add you with: gem owner guard-minitest --add rmm5t

@rymai do you have the permission access to add @rmm5t on rubygems? I'm not the author of that one.
