Problem:
`:help dev-name-common` states that "buf" should be used instead of
"buffer" but there are cases where buffer is mentioned in the lua API.
Solution:
- Rename occurrences of "buffer" to "buf" for consistency with the
documentation.
- Support (but deprecate) "buffer" for backwards compatibility.

This was added before there was a dedicated language server for
tree-sitter queries. Now that https://github.com/ribru17/ts_query_ls
exists, this is a better option in every regard (and up to now
required manually disabling the builtin linter to avoid duplicate
diagnostics and performance issues).
It seems that nvim-treesitter stops treesitter highlight when changing
filetype, so it makes sense for builtin ftplugins to do this as well.
Use :call and v:lua here to allow separation with '|'.
