Support in-support Ruby versions only? about rainbow

[olleolleolle]

Right, so 3.0 dropped today, and we can't run the same Gemfile with it and the older things. Wrong!

Ruby 2.5: EOL date: 2021-03-31

Oh, interesting. What's the oldest 2.x version we could have with the same Gemfile supporting 3.0?

[olleolleolle]

@sickill Haha, I was just out of date, in my development checkout. Haha.

@sickill Here's an example where we'd need to wiggle around to support 3.x - using a separate Gemfile _could_ perhaps make it possible. Perhaps only time would make it possible.

➜  rainbow git:(master) ruby -v
ruby 3.0.0p0 (2020-12-25 revision 95aff21468) [x86_64-darwin20]
➜  rainbow git:(master) bundle

listen-3.2.1 requires ruby version >= 2.2.7, ~> 2.2, which is incompatible with
the current version, ruby 3.0.0p0
➜  rainbow git:(master)

Aha, update: https://github.com/guard/listen/releases Supports 3.

https://endoflife.date/ruby lists the published dates in a neat little table.

I kind of want to get a release out with the old code, what's in trunk right now, and then have a clean slate to think of what we can do.

OK, since Ruby 2.3 on AppVeyor does this: I want to cut it from the list of supported Ruby versions.
