UnboundMethod#bind_call is 2.7+ only

[headius]

The uri gem does not specify a minimum Ruby version, but it implicitly requires 2.7+ due to the use of UnboundMethod::bind_call.

JRuby 9.2 available today supports 2.5. JRuby 9.3 due out soon will support 2.6. We will not have a 2.7+ release until JRuby 9.4 later this year.

Is it necessary to use bind_call here? I believe this is the only thing that would prevent the gem from being usable on JRuby 9.2.

There are only two places using bind_call, both inspect methods in the RFC parsers.

I'm fine making bind_call optional and setting required_ruby_version to whatever the earliest version is that passes the specs (after adding specs for inspect). I'll submit a PR for that.
