Updates all `help()` output to use the phrase: `For online docs please visit http://docs.micropython.org/` Some ports previously used different wording, some pointed to the wrong link. Also make all ports use `help.c` for consistency. This work was funded through GitHub Sponsors. Signed-off-by: Jim Mussared <jim.mussared@gmail.com>
