Drop support for Ruby 3.1 as it is EOL

[larouxn]

Ruby 3.1 is EOL as of earlier this year last year (source) and as such we should probably drop support like #632 did for Ruby 3.0. Additionally this repo/gem's CI doesn't even test Ruby 3.1 anymore as of #653 from July 31st of this year. Thus, it's in fact a bit risky to still allow Ruby 3.1.

Inspired by #631

The bookworm (oldstable) release of Debian uses Ruby 3.1 as its default and it is supported until 2026.

Not saying that we have to support Debian, but I've been using Debian as a gauge for the gems that I support. (I don't run Debian, it was just brought up to me on another gem and the request seemed sound to me)

That's an interesting a fair point regarding Debian. While I would prefer to drop support for Ruby 3.1 as it's EOL, I am not a maintainer nor (yet) contributor to this gem so I'll leave it up to such people to decide.

That said, if we do intend to continue allowing Ruby 3.1 installs until 2026 we should add it back to CI.

Good point.

To be clear, I do not maintain this gem. (have contributed for 9 years)
That was just something I threw out there based upon comments given to me when I tried to drop older versions of ruby

👋 Any chance we can get this merged? Ruby 3.1 is now over 9 months passed EOL.

Heck at this rate we're coming up on Ruby 3.2 EOL at the end of March. 😅
