Environment details

• OS: LInux
• Node.js version: n/a
• npm version: n/a
• release-please version: Using v3 of the release-please-action so whatever version is used there.

Steps to reproduce

See #2078 for the background. I found that with any type of commit/merged PR, release-please was generating a new release, even for just chore commits, which I thought shouldn't happen.

My release-please-config.json was originally this:

{
  "changelog-type": "github",
  "packages": {
    ".": {
      "release-type": "go",
      "extra-files": [
        "README.md",
        "main.go"
      ]
    }
  }
}

I had added the changelog-type setting to see what the difference was in the generated changelog, removing it so my release-please-config.json looks like this:

{
  "packages": {
    ".": {
      "release-type": "go",
      "extra-files": [
        "README.md",
        "main.go"
      ]
    }
  }
}

And now normal behaviour is restored.
