* Make sure to always use the right `warn`

* lib/bundled_gems.rb: more reliable caller detection

The `2` skipped frames went out of sync and now it should be `3`.

Rather than just update the offset, we can implement a way that
is adaptative as long as all require decorators are also called require.

Also we should compute the corresponding `uplevel` otherwise the
warning will still point decorators.

* Warn ostruct for Ruby 3.5

* Warn pstore for Ruby 3.5

* Mark rdoc as bundled gems at Ruby 3.5

* Warn to use win32ole without Gemfile for Ruby 3.5

* EXACT list is mostly same as SINCE list on bundled gems.

* Mark to warn fiddle as bundled gems for Ruby 3.5

* Mark to warn logger as bundled gems for Ruby 3.5

* We should use uplevel:2 in another case.

Like the following scenario with bootsnap, that frames are same or smaller than frame_to_skip(=3).
