## Summary

Add `!fuzzy-ruby-server` to the Ruby language servers list in the
default settings so it is opt-in rather than enabled for all users by
default.

This is a prerequisite for merging the Fuzzy Ruby Server support in the
Ruby extension: https://github.com/zed-extensions/ruby/pull/283

As requested by @vitallium in the review comment:
