fix(docs): point gitConfig at the current repository name (#12364)

The docs site declared `gitConfig.repo = 'framework'`, the pre-rename name.
`objectstack-ai/framework` and `objectstack-ai/objectstack` return the same
repository id (1136691870), so the old name is a rename redirect: every GitHub
URL the site emitted resolved, but only after a 301.

Three link types are built from this one constant -- the nav bar's GitHub link,
the homepage hero's GitHub button, and each doc page's "edit this page" link --
and PR for the JSON-LD work emits `SoftwareSourceCode.codeRepository` from it
too, where a stale name is a machine-readable identity claim rather than a link
a human clicks through.

Measured on a local production build: stale-name occurrences across all
prerender artifacts went 3656 -> 0, and all three link types now answer
HTTP/2 200 with no `location:` header where they previously answered HTTP/2 301.
