Subject: [PATCH] feat: print commit message when the message is invalid

When using the CLI, if the message is invalid we lose all its content (using a custom message in VIM mode), which might be a little frustrating when we a have a long commit body.

This feature prints the full message when there are linting errors.

Closes #222
