feat: check disable_pattern exists and notify if not

## Details

Related issues:

- #386
- #388

The current approach of assuming that most people with dev builds would
update on new releases does not hold true enough.

Take a similar approach as the pcall around `nvim_buf_set_extmark` and
notify users that they should update with a more targeted error message
rather than bubbling up a stack trace when things fail.
