Closes#33510https://github.com/zed-extensions/php/issues/29
If certain language servers do not provide an insert/replace range, we
use `surrounding_word` as a fallback for that range, which internally
uses `word_characters`. It makes sense to use
`completion_query_characters` instead of `word_characters` to get that
range, because we use `completion_query_characters` to query completions
in the first place.
That means, for some hypothetical reason (e.g., if the Tailwind server
stops providing insert/replace ranges), we would correctly fall back to
the range "bg-blue-200^" instead of "200^", because
`completion_query_characters` includes "-" in this case.
For this particular fix, right now the default PHP language server
`phpactor` does not provide an insert/replace range, and hence
completion query character is used, which is `$` in this case.
Note that `$` isn't in word characters for reasons mentioned here:

Release Notes:
- Fixed an issue where accepting variable completion in PHP would result
in a double $ sign in the prefix.
