www-apps/cgit: re-add 9999 series to support much newer Git

Upstream has not made an official release since 2020, but master is more
up to date, and trusted contributers have a branch with the latest Git
support.

This is important because Git v2.45.0 adds support for Bloom Filters in
commit graphs, providing 10x performance in web displays.
