Description

Running docker build --builder=someremote --build-arg BUILDKIT_SYNTAX=... against a BuildKit instance where the dockerfile.v0 frontend is disabled doesnt work

Expected behaviour

I expected that the docker image spec provided to BUILDKIT_SYNTAX would be used via the gateway.v0 frontend

Actual behaviour

ERROR: failed to solve: invalid frontend: dockerfile.v0

Buildx version

github.com/docker/buildx v0.9.1-docker ed00243a0ce2a0aee75311b06e32d33b44729689
