Override target configurations from command line.
Override target configurations from command line. The pattern matching syntax is defined in https://golang.org/pkg/path/#Match.
Example:
```
docker buildx bake --set target.args.mybuildarg=value
docker buildx bake --set target.platform=linux/arm64
docker buildx bake --set foo*.args.mybuildarg=value # overrides build arg for all targets starting with 'foo'
docker buildx bake --set *.platform=linux/arm64 # overrides platform for all targets
```
