driver: Move -fdiagnostics-urls= early like -fdiagnostics-color= [PR114980]

In GCC 14 we started to emit URLs for "command-line option <option> is
valid for <language> but not <another language>" and "-Werror= argument
'-Werror=<option>' is not valid for <language>" warnings.  So we should
have moved -fdiagnostics-urls= early like -fdiagnostics-color=, or
-fdiagnostics-urls= wouldn't be able to control URLs in these warnings.

No test cases are added because with TERM=xterm-256colors PR114980
already triggers some test failures.

gcc/ChangeLog:

	PR driver/114980
	* opts-common.cc (prune_options): Move -fdiagnostics-urls=
	early like -fdiagnostics-color=.
