chore(catalog): bump Linear Integration to v0.3.0 (repo renamed to spec-kit-linear-sync) (#2893)

* chore(catalog): bump linear to v0.3.0 + spec-kit-linear-sync URLs

The Linear extension repo was renamed ashbrener/spec-kit-linear -> spec-kit-linear-sync
and shipped v0.3.0. Update the community catalog entry's download_url (was pinned to
v0.2.0), repository/homepage/documentation/changelog URLs, and version. extension id
stays 'linear' (commands unchanged); old GitHub URLs redirect.

* docs(community): point Linear extension table row at spec-kit-linear-sync
