[ruby-core:119305] [Ruby master Bug#20714] Handle optional dependencies in `bundled_gems.rb`

Issue #20714 has been updated by deivid (David Rodr=EDguez).


I think this would affect both Bundler and non Bundler usages. Currently th=
e warnings recommends to install the gem from RubyGems in non Bundler conte=
xt, that will also be lost in Ruby 3.4 for gems like `csv`.

That said, I also tend to think this is an acceptable compromise. As @hsbt =
noticed, users upgrading directly from Ruby 3.2 to 3.4, or in general users=
 used to the old Ruby 3.2 behavior that fail to see the Ruby 3.3 warnings f=
or whatever reason may find this a bit harder. But I expect most users will=
 go through Ruby 3.3 at some point and get some heads up about this.

----------------------------------------
I've encountered a few places around bundled gems where the library doesn't=
 care if the gem is available, but will still provide some functionallity i=
f it is.

The way to accomplish that right now seems to be by setting `$VERBOSE =3D n=
il` and resetting it later again to not bother the user with the warning ab=
out the gem. However, this has the effect of silencing the warning about ot=
her gems as well, that may not be prepared about the bundling.=20

>>From `ruby/reline` for example: https://github.com/ruby/reline/blob/c90f08f=
7e308d2f1cdd7cfaf9939fe45ce546fd2/lib/reline/terminfo.rb#L1-L15
Or the `logging` gem: https://github.com/TwP/logging/blob/df41715364f7eb8c6=
5098cd3c3316677ef1f3784/lib/logging.rb#L9-L15

I propose to simply delay the warning to the next require.
