This is based on the PR (https://github.com/spantaleev/matrix-docker-ansible-deploy/pull/3241)
by Tobias Diez (https://github.com/tobiasdiez).

I've refactored some parts, made it more configurable, polished it up,
and it's integrated into the playbook now.

Both the WeChat bridge and WeChat agent appear to be working.
The WeChat bridge joins rooms and responds as expected.

That said, end-to-end testing (actually bridging to a WeChat account) has not been done yet.

    Rename WeChat Agent configuration file

    This makes it more clear that it belongs to the agent.
    Otherwise, `config.yaml` and `configure.yaml` make you wonder.

    Update WeChat logging config

    This brings it up-to-date with what mautrix-go uses.
    Otherwise, on startup we see:

    .. and it gets migrated to what we've done here.

    Make sure matrix-wechat-agent runs as 1000:1000

    It needs to write stuff to `/home/user/.vnc`.

    `/home/user` is owned by `user:group` (`1000:1000`), so it cannot run
    any other way.

    Previously, if the `matrix` user was uid=1000 by chance, it would work,
    but that's pure luck.

    docker_src -> container_src in WeChat bridge

Date:   Mon Jun 3 17:54:24 2024 +0300

    matrix_go_wechat_ -> matrix_wechat_

    The bridge is written in Go, but does not include Go anywhere in its
    name. As such, it's mostly useless to use `matrix_go_wechat` as the
    prefix.
