[Buildroot] [git commit branch/2025.08.x] docs/manual: update old git links to proper gitlab location

[Titouan Christophe]

commit: https://git.buildroot.net/buildroot/commit/?id=81431493764b414cc01001b76d28a29d6cc732cd
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2025.08.x

Some links are still pointing to git.buildroot.org, which is the old URL
for the official Buildroot git repository. The repository is now hosted
at gitlab.com. Update those old links accordingly.
