Fix pydabs acceptance test regex to match v1.x bundle versions (databricks#5294)

The `acceptance/bundle/templates/pydabs/test.toml` replacement regex
only matched `databricks-bundles==0.x.y`, so after the v1.0.0 release
the wheel version `1.0.0` slipped through unredacted and the recorded
output (`databricks-bundles==x.y.z`) no longer matched.

Broaden the regex to `\d+\.\d+\.\d+` (and escape the dots) so any future
version is normalized.
