docs(docker): add an example of building distroless image (#1900) Related to https://github.com/php/frankenphp/issues/151, this PR adds an example about how building a distroless image for a Frankenphp project. FYI, on https://github.com/dunglas/symfony-docker, it only saves ~24MB in the image size. I think we could go even further by building our own distroless image with Bazel like they do [here](https://github.com/GoogleContainerTools/distroless) but for now, the doc is a good start. --------- Co-authored-by: a.stecher <a.stecher@sportradar.com> Co-authored-by: Alexander Stecher <45872305+AlliBalliBaba@users.noreply.github.com>
