The BuildWebsite / PublishWebsite Dagger functions did not set
HUGO_PARAMS_GITVERSION, so the <meta name="x-version"> tag was never
rendered in the deployed HTML. website-verify.sh checks for that tag
and always timed out / failed.
Add an optional commitHash parameter to both functions and wire it
through as HUGO_PARAMS_GITVERSION (the env-var pattern Hugo uses to
inject params from the environment). Update task publish-website to
compute and pass the short git hash, matching how deploy-linux already
handles this.
Closes#360
