Description

Bumping the version from 5.4.0 to 5.5.0 broke the usage of target "docker-metadata-action" {} with docker/bake-action@v4. When using 5.4.0, I was able to override the tags defined in my docker-bake.hcl file with the outputs of the docker/metadata-action, but now the tags no longer get overwritten with 5.5.0.

Expected behaviour

I would expect that if I have the following in my docker-bake.hcl file, the output of docker/metadata-action@v5.5.0 would override the tags defined in the targets.
``
target "docker-metadata-action" {}

target "_common" {
inherits = ["docker-metadata-action"]
}

target "example1" {
inherits = ["_common"]
tags = ["example1:latest"]
}
``

Actual behaviour

The outputs from docker/metadata-action@v5.5.0 do not override the tags defined in my docker-bake.hcl. When using v5.4.0 of docker/metadata-action, the tags were successfully overwritten.
