Fix docker networking when no reverse-proxy is used

For example, synapse-admin connects to additional networks here:
c0559870b5/roles/custom/matrix-synapse-admin/templates/systemd/matrix-synapse-admin.service.j2 (L39-L41)

This defaults to 'traefik' through
matrix_playbook_reverse_proxy_container_network, which is not correct in
case matrix_playbook_reverse_proxy_type is set to none.

Update dependency charset-normalizer to v3.4.1

* Add logout_redirect_url var and option templating for matrix element client

* Simplify logout_redirect_url templating and make it safer

Using `to_json` to make it safer.

Judging by the code here 0b24d33c64/src/Lifecycle.ts (L1026-L1032)
it doesn't seem like it leaving `logout_redirect_url` empty will hurt, so this patch removes the `if` block.

* Add comment for the `matrix_client_element_logout_redirect_url` variable

We were overriding the `matrix_bot_matrix_registration_bot_matrix_homeserver_url` variable via `group_vars/matrix_servers`
to point it to the container-local homeserver URL, but this variable was not being used at all.

The actual variable name (which was being used) is `matrix_bot_matrix_registration_bot_api_base_url`.

Consistent "send help" messages

Signed-off-by: Suguru Hirahara <acioustick@noreply.codeberg.org>

The common pattern is "Send `.*?` to the bot (in the room) to see the available commands." If the descripions are about a bot being invited to a certain existing room or room which is not DM, then "in the room" is inserted among them.
