Get rid of bundler deprications

[jontrossbach]

Bundler 2 deprecated multiple flags and is backwards compatible only back to 2.3.0.

This is how I interpreted the updates.

Thanks for the PR!

On a brief look it looks good, but please drop the changes for unsupported Ruby versions (they're there for archive purposes only).

Please also note that Ruby containers have various Bundler versions, so the syntax may not be supported by some older versions (e.g. 1.X).

There's also Ruby 3.0 I think you've not covered.

Thanks @pvalena! I amended my interpretation of the changes you recommended to this commit. Let me know if you have anymore feedback.

I hope we run the tests still the same way.

Thinking about it. Let's not disrupt existing containers. @jackorp maybe implement this for 3.1? :)

@jackorp I've tried this in my fork / branch, and it seems to work. Anything against using this for 3.1?

@jontrossbach @pvalena Please if this pull request is still valid, rebase it against master and add to the newest versions like 'ruby-3.1'.

Otherwise close this issue.

Look like we already have it in 3.1 and 3.0 through other commit. +1 for closing.
