(MAINT) Add authorized account for live branch targeting

[michaeltlombardi]

PR Summary

Prior to this change, the GHA workflow for checking authorization on submitting PRs to the live branch didn't include the authorized_accounts parameter.

When you retrieve the permissions for the learn-build-service-prod[bot] account, the API reports that the automation account lacks all permissions.

This change adds the bot account to an allow-list to prevent the error.

Pull request overview

This PR adds the learn-build-service-prod[bot] account to an allow-list for the live branch authorization workflow. The bot account requires this allow-listing because the GitHub API reports it lacks all permissions when checked programmatically, which would otherwise cause the authorization workflow to fail for legitimate automated PRs targeting the live branch.

Changes:

• Added the authorized_accounts parameter to the authorization action with the bot account name
