[(pushed)] sphinx: update diagnostics URLs

  For the future, we'll use https://pypi.org/project/sphinx-redirect-by-id/
which will allow links like

https://gcc.gnu.org/onlinedocs/gcc/redirect.html?q=cmdoption-Wfoo

but for now, let's use the proper landing pages.

Martin

gcc/ChangeLog:

	* opts.cc (get_option_html_page): Port to sphinx URLs.
	(get_option_url): Likewise.
	(test_get_option_html_page): Likewise.

Do we need a redirect at the old location?

Well, what's not working are older gcc releases that still point to "master" branch
documentation:

gcc --version
gcc (SUSE Linux) 12.2.1 20221020 [revision 0aaef83351473e8f4eb774f8f999bbe87a4866d7]
...
https://gcc.gnu.org/onlinedocs/gcc/Warning-Options.html#index-Wunused-parameter

these should point ideally to:
https://gcc.gnu.org/onlinedocs/gcc-12.2.0/gcc/Warning-Options.html#index-Wunused-parameter

anyway, we can provider redirect for these, I'll ask Gerald.

I suppose we might want to point to the "latest" 12 version, so have a
gcc-12/ link and use that?
And have a releasing.html entry saying to adjust those URLs in source
to point to the new
version instead of trunk?
