cleanup unused chart values + change mongo default (#2484)

- Removes chart values that are unused
- Also change `local-mongo.default` -> `local-mongo`,
`local-minio.default` -> `local-minio` as some users have reported
issues with `.default` and it will certainly break if not deploying
Browsertrix in the `default `namespace.
