Could not parse GitHub App user which include brackets

[henri-hulski]

I'm using GitHub Actions for release and deploy. The git user is an organization GitHub App which has all necessary permissions.
The problem is that GitHub App users have square brackets in there user name and email.
So when running

gh-pages -d build -b master -r https://github.com/myorg/myrepo.github.io.git -u "mygithubapp[bot] <123456789+mygithubapp[bot]@users.noreply.github.com>"

I get the following error.

Error: Could not parse name and email from user option "mygithubapp[bot] <123456789+mygithubapp[bot]@users.noreply.github.com>" (format should be "Your Name <[email protected]>")

It seems that the email parser you are using (email-addresses) doesn't accept brackets neither in the username (only if quoted) nor in the email (I think here is no workaround). See also jackbearheart/email-addresses#52.
Any way to fix that? Maybe just using a custom regex?
