Mise wipe RUBYLIB value when working with RubyMine

[DmitryPogrebnoy]

Describe the bug
There is a bug with RubyMine and Mise - RUBY-32547.
RubyMine patches RUBYLIB env variable when running tests. But it doesn't work with Mise, because Mise wipes RUBYLIB in the method get_pristine_env (src/env.rs:300), after applying remove RUBYLIB patch.

To Reproduce

1. Install RubyMine (2024.1 or later, even EAP versions).
2. Install mise 2024.7.1.
3. Run RubyMine from terminal using bash script.
4. Use sample rails project from the ticket RUBY-32547.
5. Run tests in users_controller_test.rb.

Get an exception like:

/bin/bash -c "export PATH=$PATH:/home/karinamokleva/.local/bin && /home/karinamokleva/.local/bin/mise exec --quiet ruby@3.3.0 -- /home/karinamokleva/.local/share/mise/installs/ruby/3.3.0/bin/ruby -x /home/karinamokleva/RubymineProjects/test_2024.1.1_preview_rails33/bin/bundle exec /home/karinamokleva/.local/share/mise/installs/ruby/3.3.0/bin/ruby -Itest /home/karinamokleva/Downloads/RubyMine-242.10148/plugins/ruby/rb/testing/runner/tunit_or_minitest_in_folder_runner.rb"

Process finished with exit code 1

Expected behavior
Tests run successfully.

Additional context
When RubyMine run tests it patches RUBYLIB variable and adds there several paths. But Mise drop RUBYLIB completely. I debugged it to the method get_pristine_env (src/env.rs:300) in Mise repository and for some reason patches from __MISE_DIFF is

[
    Remove(
        "RUBYLIB",
    ),
]

which is wrong. Mise should preserve RUBYLIB patches to be able to work with RubyMine.
