Add `--no-build-id` automatically on CI

[Hofer-Julian]

Creating an unique folder per build can be useful for local development, but on CI you probably want a folder with a constant path to make caching easier.

We could enable --no-build-id automatically on CI.

Alternatively, we should document this pattern

Yeah I think if we want that, we should deprecate this option and instead have option like:

--build-id=auto (set locally, not on CI)
--build-id=my-build-id (set to fixed string)
--build-id=yes/no | true/false
