Load worktree settings when loading options for language servers (#7615)

Previously we only looked at the global settings, this changes that to
start looking in local settings first and then fall back to global ones.

Fixes #4279.

Release Notes:

- Fixed language server configurations not being picked up from local,
worktree-specific settings.
([#4279](https://github.com/zed-industries/zed/issues/4279)).
