Closes https://github.com/spantaleev/matrix-docker-ansible-deploy/pull/4039
Partially reverts 30dad8ba277bc32494125b70794e2d0df5ac08ae which renamed
`config.yml` to `config.yaml` in the playbook and on the server, for
consistency with the rest of the playbook.
The problem is that:
- baibot defaults to looking for `config.yml`, not `config.yaml` (as provided).
This can be worked around by specifying a new `BAIBOT_CONFIG_FILE_PATH=config.yaml`
environment variable. This brings more complexity.
- renaming the target file (on the server) to `config.yaml` means people
with an existing installation would drag around the old file (`config.yml`) as well,
unless we create a new Ansible task (`ansible.builtin.file` with `state: absent`) to remove
the old file. This brings more complexity as well.
https://github.com/spantaleev/matrix-docker-ansible-deploy/pull/4039 adjusts where the file is mounted,
which fixes the immediate problem (baibot not starting), but still means
people will end up with 2 config files for baibot (`config.yml` and `config.yaml`).
This patch, reverts a bit more, so that we still continue to use `config.yml` on the server.
People who have upgraded within the last ~17 hours may end up with 2 files, but it shouldn't be too many of them.
