php8.1: update to 8.1.8, add changelog URL, fix man pages
https://github.com/void-linux/void-packages/pull/37949

Description:
The changelog URL points to the changelog for $version because the
changelog in the master branch contains the details of many alpha and RC
releases, which makes it difficult to find the changelog corresponding
to the current pkgver.

I've also changed the `.so` directives in man pages to point to the
correct man pages. Previously they pointed to the man pages of php 7.4
