fix: fix commit message

Following changes are based on this pull request:

• Moved commit message to commit-from-action constructor
• feat: Added new input “jsonFinalNewline” (true by default) (this one is pretty important, thank you)

The missing space between the commit message prefix and the static part is intended to keep as much freedom as possible. This is why the default commit message prefix is “autofix: ” and not “autofix:”.

@Jaid Yeah you're right, I basically changed it because it wasn't possible to add a whitespace. But the other merged solution fixes it anyway.

Apart from that: They merged a PR in actions/toolkit recently where they added a trimWhiteSpace option to getInput. I think it's not released yet, but in the future this might be a solution, in case whitespaces should be kept in the input.
