ci: remove OIDC claim debug step — pipeline is green

Run 24637725063 published all 8 @perryts/perry* packages to npm at
0.5.106 (workflow ✓, all sigstore-provenance-attested, latest dist-tag
moved off 0.0.1-bootstrap placeholders). The debug step was only
needed to prove the OIDC claim fields matched the Trusted Publisher
config; it showed everything matched, which pointed at npm/cli#9088
(fixed in c7cc823 by upgrading npm to >= 11.5.1).
