<doc>(docker-compose): add a config for M1 developer to build image

[david30907d]

Why: I was setting up breeze on my M1 mac and bumped into this issue

Tested by: add the platform flag and then ./breeze --python 3.8 --backend mysql works fine

This is a band-aid really and I really hope #15635 will be solved soon and that we will solve it "well". Having to uncomment line in a file that no-one knows, without documentation and full explanation is really not going to be discoverable. Let's wait for a good solution (We are waiting for apache-beam release - RC3 is being voted now).

I will close that one for now - if it turns out that the "good" M1 support for development will not be there soon and there will be other obstacles, we might revisit that (but then any such change shoudl start with documentation in CONTRIBUTING : "if you are M1 Mac user ....." .
