Update ghcr.io/element-hq/element-web Docker tag to v1.11.108

On ansible-core 2.19.0, invoking macro like this (which only outputted
something in its `if` block, not in `else`), resulted in a macro
outputting `None`.

One way to work around it is to add an explicit `else` block which also
outputs something.

A better way to work around it is to only invoke the macro if it
has something to output.

ansible-core>=2.19.0 only auto-parses YAML files, not JSON.

Previous ansible-core versions auto-parsed JSON as well, but ansible-core>=2.19.0
doesn't, so we added a `from_json` post-filter.
However, older versions auto-parsing JSON and turning it into a dict, on
which we later run `from_json` is no good.

In this patch, we try to equalize behavior and configure Ansible to never parse JSON,
hopefully making old-Ansible behave like new Ansible.

We expect a string, which is parsed via `from_json`.

This matches previous usage in inventories, as well as what the
user-controlled precedessor of this variable (`matrix_synapse_admin_configuration_extension_json`)
is like.

Most `when` dict keys already were done correctly, but these few weren't.

ansible-core 2.19.0 reported the following errors for them:

> [WARNING]: Deprecation warnings can be disabled by setting `deprecation_warnings=False` in ansible.cfg.
> [DEPRECATION WARNING]: The `bool` filter coerced invalid value 'variable_name' (str) to False. This feature will be removed from ansible-core version 2.23.

It seems like ansible-core 2.19.0 no longer automatically parses template lookup content
as JSON (into a dict) when dealing with template files (be it `file.json.j2` or `file.j2`).

For files detected to contain YAML (`.ya?ml.j2`, but possibly others),
it automatically parses YAML, because the `convert_data` option
for the template lookup defaults to `true`.
