boolean input fix, improved language, auto detect parent

[splitice]

This resolves #46 and #3

I also did some minor dependabot merges. I left the bigger ones that need more specific testing (but are probably fine).

Bumped version to 1.6.0

1.6.1

Added a default value for ignore_fail to comply with github actions schema for boolean values

1.6.2

Added auto_merge: I kept the default behaviour (but the default is pretty dangerous if you ask me)

Thanks a lot.
