[issue33422] Fix and update string/byte literals in help()

[Andrés Delfino]

New submission from Andrés Delfino <adelfino at gmail.com>:

Right now, for string/byte literals help() shows, for example:

No Python documentation found for 'r'.
Use help() to get the interactive help utility.
Use help(str) for help on the str class.

PR fixes the quotation mark removal and updates the list with f and u literals, while also adding uppercase versions of all literals. While the list is install incomplete (e.g., fR and the others could be listed) I believe that's too much.
