Minor behavior changes

Changes that may cause incompatibilities for some users, but should not for most

• tls: if both match_subject_alt_names and match_typed_subject_alt_names are specified, the former (deprecated) field is ignored. Previously, setting both fields would result in an error.

Changes expected to improve the state of the world and are unlikely to have negative effects

• docker: update Docker images (distroless -> d65ac1a) to resolve CVE issues in container packages.
