fix(firefox-syncserver): fix to use PostgreSQL instead of SQLite (#2669)

* Fix to set FF_SYNCSERVER_SQLURI instead of DB_HOST.

This enables PostgreSQL as intended, instead of the upstream SQLite default.

* Bump version to 6.0.19

* Bump version to 7.0.0 as it's a breaking change

* Revert changes to helm-values.md since it's auto generated
