[wwwdocs, committed] Fix link to "Feature Test Macros" in "Porting to GCC 14" page

[Martin Jambor]

Hi,

Michal Jireš found out that the link to Feature Test Macros on the
Porting to GCC 14 page was broken, it misses a "/latest/" directory in
the middle of the path.

I'll commit the following as obvious.

Thanks,

Martin
