Limit --help and --help-hidden to 100 character line length (#58835)
Just fixing the command line description to make sure it is not more than 100 characters wide as discussed with @oscardssmith in PR #54066 and PR #53759. I also added a test to make sure that nothing more than 100 characters is inserted. Thank you.
