Fix version format for weekly release tags

Weekly release tags (refs/tags/release/weekly/*) were falling through
to pull request version format, producing malformed package versions
like '0.1.250929-pull-.2302' instead of '0.1.250929-build.2302'.

Added startsWith(github.ref, 'refs/tags/release/') to VERSION_PROPERTY
condition so release tags use build.RUNNUMBER format like main branch.

Fixes version suffix for both build and package jobs.

Evidence: Run 18109399189 artifacts showed all packages with 'pull-.'
instead of 'build.' format.
