pulumi: build from git checkout so version is correct

When built using the source provided tarballs from upstream, the
embedded version number in the binary is incorrect, since it based on
git tags, which are not present in the source tarball, leading to
`pulumi version` to report 0.0.0 instead of `0.16.11`

Closes #36162.
