credential type is not a secret

[jakecoffman]

I noticed the type is being hidden:

    "credentials-metadata": [
      {
        "type": "***",
        "host": "github.com"
      },
      {
        "type": "***",
        "url": "https://maven.pkg.github.com/github/*"
      },

There's no need to do that so I've added it to the non-secret allow list.
