libstdc++: Fix mainpage.html link to Doxygen docs [PR109965]

Doxygen renamed the "Modules" documentation to "Topics" a few years ago
to avoid confusion with C++20 Modules:
https://github.com/doxygen/doxygen/issues/8772

This updates our internal link to 'modules.html' so that it refers to
'topics.html' instead.

libstdc++-v3/ChangeLog:

	PR libstdc++/109965
	* doc/doxygen/mainpage.html: Link to topics.html instead of
	modules.html
