add minimal docker compose setup

[Nathan-Yorio]

Hi, found this while browsing around for a tool like this and have in my fork a setup with this to build and run it under docker compose. Since it's a simple webui, it works pretty easily to run it this way.

I know it's a totally unprompted PR so of course feel free to reject or suggest changes, but I thought why not I'll share :shrug:

A few points:

• don't know exactly if it's cross platform ish, since I don't have a mac or windows machine to test on
• added entrypoint sh to run and execute, in case functionality expands and needs flags or checks
• I mapped the data storage location as ~/.local/share/mycolog since I don't think it would be so good to map in the whole ~/.local/share to the container

runs with docker-compose up or docker compose up

Hi Nathan, thanks for reaching out! At the moment I don't have a motivation to advertise different ways of running mycolog. As Go binaries don't have any runtime dependencies, I don't see any benefit of running mycolog in a docker container.

Thus I'm not inclined to merge this pull request right now. If, however, I hear of someone having problems with running the program, I'll redirect them to this pull request.

Totally fair and understandable. Thanks for the response :)

Thanks for your understanding.
