Promote flag default doesn't agree with docs

The default value in the action.yml is true. Are you seeing a different behavior?

[joeyparrish]

Yes. I was passing a value that happened to be blank due to a dumb workflow bug.

    with:
      promote: ${{ env.APPSPOT_PROMOTE }}

That variable was meant to be "true" or "false", but it was left out of the environment entirely. It would appear that the default in action.yml was not used in this case.

This didn't become obvious until I upgraded from v0 to v2, since v0 had the default implemented explicitly in TypeScript.

Right - if you pass in a value, it will use the empty string (whereas not providing a value uses the default).

Thanks!
