Commit messages with single quote throw a syntax error.

Received the following message from the Github Action -

[NOTE] Pushing git commit with "Add a github action to split the plugin into it's own repository in order to release composer packages." message to "main"

sh: 1: Syntax error: Unterminated quoted string

I believe the commit message needs to be escaped when used in the git commit.
