synapse: delete unnessary parts of the default config

(i.e. those parts which are managable by nix, and a couple which were defined
twice were deduplicated)

-      ## TLS ##
-      
-      # PEM-encoded X509 certificate for TLS.
-      # This certificate, as of Synapse 1.0, will need to be a valid and verifiable
-      # certificate, signed by a recognised Certificate Authority.
-      #
-      # See 'ACME support' below to enable auto-provisioning this certificate via
-      # Let's Encrypt.
-      #
-      # If supplying your own, be sure to use a `.pem` file that includes the
-      # full certificate chain including any intermediate certificates (for
-      # instance, if using certbot, use `fullchain.pem` as your certificate,
-      # not `cert.pem`).
-      #
-      #tls_certificate_path: "CONFDIR/SERVERNAME.tls.crt"
-      
-      # PEM-encoded private key for TLS
-      #
-      #tls_private_key_path: "CONFDIR/SERVERNAME.tls.key"
-      
-      # The minimum TLS version that will be used for outbound federation requests.
-      #
-      # Defaults to `1`. Configurable to `1`, `1.1`, `1.2`, or `1.3`. Note
-      # that setting this value higher than `1.2` will prevent federation to most
-      # of the public Matrix network: only configure it to `1.3` if you have an
-      # entirely private federation setup and you can ensure TLS 1.3 support.
-      #
-      #federation_client_minimum_tls_version: 1.2 # also eigentlich will ich ja 1.3 und wieso zur hölle das nicht standard ist, keine Ahnung. Ich lass die Option mal drin, dass wir ran kommen, wenn 1.2 engültig broken ist

-      ## Database ##
-      
-      # The 'database' setting defines the database that synapse uses to store all of
-      # its data.
-      #
-      # 'name' gives the database engine to use: either 'sqlite3' (for SQLite) or
-      # 'psycopg2' (for PostgreSQL).
-      #
-      # 'args' gives options which are passed through to the database engine,
-      # except for options starting 'cp_', which are used to configure the Twisted
-      # connection pool. For a reference to valid arguments, see:
-      #   * for sqlite: https://docs.python.org/3/library/sqlite3.html#sqlite3.connect
-      #   * for postgres: https://www.postgresql.org/docs/current/libpq-connect.html#LIBPQ-PARAMKEYWORDS
-      #   * for the connection pool: https://twistedmatrix.com/documents/current/api/twisted.enterprise.adbapi.ConnectionPool.html#__init__
