This adds the matrix_hookshot_connections variable for configuring
static webhook connections via the config file.

See: https://github.com/matrix-org/matrix-hookshot/pull/1102

All these `encodedCharacters_*` settings default to `true` in Traefik v3.6.7,
so we don't need to override their values.

Ref: https://doc.traefik.io/traefik/v3.6/migrate/v3/#v367

Closes https://github.com/spantaleev/matrix-docker-ansible-deploy/issues/4835

Provoked by https://github.com/element-hq/synapse/pull/19281
which landed in Synapse v1.145.0, but we pull in a few other routes
that I noticed to be missing.

* This push request is about handling Traefik ipallowlist to synapse-admin application.

It's my first push request. If I forgot something please let me know. :-)

* Changed position of variable and naming for better expandebility of traefik options

* Remove useless `noqa var-naming` comment and too many blank lines at the end of the file
