Problem:
Some configs still reference 'lspconfig.ui.windows', which was removed
in e6569c18c21be5166e4b9cc7530e828b8285c84e.
Solution:
Remove the references.
Problem: vim.lsp.buf.execute_command has been deprecated in nightly
Solution: add version check of nvim and use client:exec_command for nightly version

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.
