[PATCH standards.texi] Update savannah URLs of config.git files

[Dmitry V. Levin]

Prefer cgit URLs over gitweb as the former are usually served faster:
$ time -f %e wget -q 
'https://git.savannah.gnu.org/gitweb/?p=config.git;a=blob_plain;f=config.guess'
1.06
$ time -f %e wget -q 
'https://git.savannah.gnu.org/cgit/config.git/plain/config.guess'
0.73

This follows the corresponding change in config.guess and config.sub scripts:
