ci(release): fix Gitea repo slug; bump to 0.6.2

The release workflow targeted mroberts/sush, which does not exist
(`tea releases list --repo mroberts/sush` returns "not found"), so the
release step would fail after building the binaries. Present since the
workflow was added in a7a561f.

Also bump softprops/action-gh-release to v2 in the unused .github
workflow; actionlint rejects v1 as too old to run.
