Fix: platform parameter is not supported by buildah config (build-without-containerfile)

[jayaddison]

Description

The buildah config command does not currently support the platform parameter.

75 introduced support for platform in both build-from-containerfile (which uses buildah bud) and build-without-containerfile (which uses buildah config).

This pull request removes support for platform during builds-without-containerfile, and raises an error if the user attempts that.

Resolves #82.

To make it more clear, can we add this input is not supported for build without containerfile in action.yml platform input?

We should make this clearer, yep :+1:

Maybe I am picking smalI details, but I wonder if we should flip that around in to a statement about where the parameter is supported: (only supported with containerfile builds)

Sounds better :+1:

To save yourself from these types of errors probably you can add git-commit hooks that are present here.

Sorry, slightly spammy with the commits here, and I realized I forgot to add sign-offs on a few of them. When we are ready I can squash down to a single signed commit.

No problem - apologies for my introducing the problem in the first place!
