Replace common.names.fullname in the default Secret name template with mastodon.fullname
This removes all Bitnami dependencies for installs not using the Bitnami PostgreSQL, Redis, and Elasticsearch. Those charts populate the common.names.fullname template value. Installs not using these charts will receive an error. Instead, use mastodon.fullname like in secrets.yaml.
