Bug Report: GraphQL mutation fails with "fileDeletions[]" parameter error

Description

The grafana/github-api-commit-action@v1.0.0 action is failing when attempting to create a commit via GraphQL mutation. The error indicates that the fileDeletions[] field requires a value separated by an '=' sign.

Expected Behavior

The action should successfully commit the staged files (chart/README.md and chart/values.schema.json) to the repository without errors.

Actual Behavior

The action fails with the following error:

field "fileDeletions[]" requires a value separated by an '=' sign
Error: Process completed with exit code 1.

Steps to Reproduce

1. Use the grafana/github-api-commit-action@v1.0.0 action with the following configuration:

- name: Commit changes
  uses: grafana/github-api-commit-action@v1.0.0
  with:
    token: ${{ secrets.GITHUB_TOKEN }}
    commit-message: "docs: helm-docs automated action [skip ci]"
    stage-all-files: true
    create-branch-on-remote: false
    success-if-no-changes: false

2. Have modified files in the repository (in this case, chart/README.md and a new file chart/values.schema.json)
3. Run the workflow

Environment

• Action Version: v1.0.0
• Runner: GitHub Actions (ubuntu-latest)
• Files being committed:
  • Modified: chart/README.md
  • Added: chart/values.schema.json

Error: Process completed with exit code 1.

Analysis

The issue appears to be in the GraphQL mutation handling. The action is trying to pass a fileDeletions parameter to the createCommitOnBranch mutation, but the parameter seems to be malformed or empty, causing the GraphQL API to reject it.
