chore(ci): correct setup-python pin comment to match v6.2.0

The pinned SHA a309ff8 resolves to tag v6.2.0, but the inline comment
read "# v6", which zizmor flags as a ref-version-mismatch. Update the
comment to the precise version, matching the rest of the workflows that
use full semver in their pin comments.

Resolves code-scanning alert #2550
