Add a `--dry-run` flag to send_custom_email management command in order to provide a mechanism to verify the emails of the recipients and the text of the email being sent before actually sending them. Add tests to: - Check that no emails are actually sent when we are in the dry-run mode. - Check if the emails are printed correctly when we are in the dry-run mode. Fixes #17767
