Description
Hi,
This is feature request is for README.md update when building from git repo.
Right now when using docker buildx a multi-arch image can be pushed to the docker hub using a git repo very elegantly.
But the README has to be updated manually or by using the hubs auto-build feature to build a unnecessary image to update README.md.
Is a update-readme option possible ?
docker buildx build -t user/repo:1.0 --platform=linux/arm,etc https://github.com/myrepo.git --update-readme --push
Here's a image of the builds with the additional "test" image, its only purpose being to update readme.

Research direction
Start by tracing the docker buildx build command and how a Git repository build is pushed to Docker Hub; the issue names no files or tests. Done means a documented --update-readme option can update the Docker Hub README during a multi-architecture push without requiring a redundant image build.
