Trigger Tableau TDVT in connectors on snapshot publish and release

Tableau users install the latest JDBC driver manually (no connector
release cycle as a buffer), so driver regressions hit them immediately -
0.9.7 and 0.9.8 both broke Tableau connections. Each publish now fires a
repository_dispatch (jdbc-snapshot / jdbc-release) into
ClickHouse/connectors, where the tableau-tdvt workflow runs the TDVT
suite against the published version and opens an issue on failure.

The snapshot version is derived from the pom <revision> property because
CHC_VERSION is commented out in nightly.yml. Both steps are
continue-on-error so a dispatch failure can never fail a publish.

Requires the CONNECTORS_DISPATCH_TOKEN secret (fine-grained PAT scoped
to ClickHouse/connectors). Refs ClickHouse/connectors#71 (CON-264).
