[Projects] OSGeo Gitea url is now gitea.osgeo.org

[Sandro Santilli]

The OSGeo Git Service official URL was moved from

  https://git.osgeo.org/gitea

to

  https://gitea.osgeo.org

Your git workflows should all still work but you may want to update your
remotes / bookmarks / links accordingly.

Shall you find a related problem please file a ticket on

  https://trac.osgeo.org/osgeo

using the SysAdmin/Gitea component

Happy hacking !
