make scissor regex independent of the language

[sionik]

This commit makes the regex used for scissor detection independent of the language of the comment.

For #13, this would be a first (very simple) step.

Apart from that, it will improve the out-of-the-box experience for any user of Helix with a language other than English set.

Does the parser actually work besides the scissors when using another language? If we want to support multiple languages in COMMIT_EDITMSG in Helix then we should probably just switch to gbprod's grammar.

Sorry for the late reply.
The parser doesn't really work, no. This commit would - with minimal effort - at least get the diff to work after the scissors.

I took a look at gbprod/tree-sitter-gitcommit, but couldn't get it to work with helix (yet).
But if you suggest that instead of building multi-language support into this parser, helix should change the parser, I'm happy to dig deeper into gbprod's repository.

In this case, I would suggest closing #13 and adding a note for this decision in the readme.

Initially I was thinking that you could have different forks of the grammar for different languages but now I think gbprod's approach is more pragmatic so we might as well switch to it if possible. Neovim is using that grammar I believe.

Yeah, if we switch to gbprod's in Helix I would deprecate (maybe archive) this repo. I probably should have closed #13 a while ago as it's a duplicate of #4.
