Documentation button on index.html (and version buttons in docs) always link to ziglang.org, even when self-hosted

[dragsbruh]

I want to self-host the Zig documentation for easier offline/local access. While testing the setup, I noticed that the Documentation button on index.html always links to https://ziglang.org/documentation/<latest>, regardless of where it's hosted.

The same applies to the version buttons on /documentation/<version>, which also link back to ziglang.org.

Would it make sense for these links to be relative, so they work properly in local/self-hosted setups (e.g. localhost:8080)?

Thanks.
