refactor: rename "server_configurations" => "configs" #3330

Problem:
The name `server_configurations` is extremely verbose and irritatingly
formal and dogmatic. This overlong name is a constant nuisance when
reading, writing, and coding.

It's also not even correct: these configurations are just as much
"client" configurations as they are "server" configurations.

Solution:
- Rename to a shorter name.
- Leave placeholder files for any old URLs that link to the old
  location.

+tools necessary to inspect and manipulate that syntax tree. It can be used to
+build formatters, linters, language servers, and more.
