actions: regenerate unpinned-tag test expected output

Adding the self_ref_dollar.yml fixture introduces one new step-adjacency
edge in the shared CWE-829 test database, which the UntrustedCheckoutCritical
query dumps under its edges relation. Regenerate the expected output to
include it. No new security findings: the $/ self-references and the
lockfile-pinned ref correctly produce no unpinned-tag results.
