Would be useful if there was documentation showing how to skip external library code when debugging the rails server using rdgb.

When I'm debugging I need to add RUBY_DEBUG_SKIP_PATH=/.asdf/ to the ENV to prevent stepping into any external code installed by asdf

example:

gdk stop rails-web && RUBY_DEBUG_SKIP_PATH=/.asdf/ GITLAB_RAILS_RACK_TIMEOUT_ENABLE_LOGGING=false PUMA_SINGLE_MODE=true rdbg --open -c bin/rails server

I think the only document that shows how to debug with rdgb is vs_code_debugging.md
