Support warning feature for bundled gems with bootsnap and zeitwerk

[hsbt]

I added some fixes from #10244

[hsbt]

@fxn @byroot This version warn correctly with Zeitwerk and Bootsnap

* Show warning with bootsnap
/Users/hsbt/.local/share/gem/gems/bootsnap-1.18.3/lib/bootsnap/load_path_cache/core_ext/kernel_require.rb:30: warning: /Users/hsbt/.local/share/rbenv/versions/3.3.0-dev/lib/ruby/3.3.0/csv.rb was loaded from the standard library, but will no longer be part of the default gems since Ruby 3.4.0. Add csv to your Gemfile or gemspec.

* Show warning with zeitwerk
/Users/hsbt/.local/share/gem/gems/zeitwerk-2.6.13/lib/zeitwerk/kernel.rb:34: warning: csv was loaded from the standard library, but will no longer be part of the default gems since Ruby 3.4.0. Add csv to your Gemfile or gemspec.

Thanks @hsbt!

FYI, I'm not sure this is totally working as intended. We're using bootsnap and previously had no issues with 3.3.0, but upon updating to 3.3.1, now seeing this:

/Users/mscrivo/.local/share/mise/installs/ruby/3.3.1/lib/ruby/3.3.0/bundled_gems.rb:130:in `<': comparison of String with nil failed (ArgumentError)

    msg = " #{RUBY_VERSION < SINCE[gem] ? "will no longer be" : "is not"} part of the default gems since Ruby #{SINCE[gem]}."

@mscrivo This change is not backport to 3.3.1 yet. Sorry, I confused with #10354
