labeler: Error: found unexpected type for label 'xxx' (should be array of config options)

Description: After upgrading to v5.0.0 and changing the labeler configuration file matching to what is outlined in the documentation, I’m receiving the following error as soon as the action starts

Run actions/labeler@v5.0.0
The configuration file (path: .github/labeler.yml) was not found locally, fetching via the api
Error: Error: found unexpected type for label 'terraform' (should be array of config options)
Error: found unexpected type for label 'terraform' (should be array of config options)

Action version: 5.0.0

Platform:

• Ubuntu
• macOS
• Windows

Runner type:

• Hosted
• Self-hosted

Repro steps:
After upgrading to 5.0.0 changed the labeler configuration to

terraform:
  - changed-files:
    - any-glob-to-any-file: terraform/**

which to me looks similar to the example from the documentation

Documentation:
- changed-files:
  - any-glob-to-any-file: docs/*

The workflow is defined as follows and used to work previously

      - uses: actions/labeler@v5.0.0
        with:
          sync-labels: true

Expected behavior: The action should run successfully.

Actual behavior: The action is failing with the error provided above.
