chore: remove code background priority override in nofile buffers

## Details

The override is no longer necessary since the default has been updated
for all buffers from `nil` to `140`. I agree with the reasoning in
[#581](#581)
that the value should also be lower than diagnostics by default.
Fix some unit tests and update docs as well.
