`-t` works on both old and new Docker versions, so it's best to use that.

This is still very far from usable.

Various bridges and bots are still talking to
`matrix-nginx-proxy` instead of the new `matrix-homeserver-proxy` role.
These services need to be reworked. While reworking them,
various cleanups are being done as well as adding Traefik-labels to
those that need them.

OpenAI changed the model a month ago and broke the bot.
This bump fixes it and adds the default model.

Use matrix_bot_chatgpt_context for CHATGPT_CONTEXT

Set OPEN_AI to matrix_bot_chatgpt_openai_pro

This container needs a writable $HOME, and will fail at startup if
there isn't one.

Provide one by pointing HOME to a path under the mounted /data
directory.
