I'm going to merge #4 into this. This is better 😅

Apologies for the merge conflicts. I let you finalize this branch.

@kevgo oh, no big deal at all! Thanks for the help 😀

I ended up naming it dprint-version just because I found "version" alone confusing because it makes me think of the action version instead (also, deno uses deno-version so this aligns with that)
