why are these keywords highlighted in my git workflow yaml file

I used the following example .yaml text

name: Deploy Plugin

on:
  workflow_dispatch:
    inputs:
      release_type:
        description: 'Type of release'
        required: true
        default: 'minor'

jobs:
  compute-inputs:
    runs-on: ubuntu-latest
    env:
      RELEASE_TYPE: ${{ inputs.release_type }}
    outputs:
      version_change: ${{ steps.compute-inputs.outputs.version_change }}
      start_time: ${{ steps.compute-inputs.outputs.start_time }}
    steps:
      - name: Compute version and time
        id: compute-inputs
        run: |
          echo "version_change=true" >> $GITHUB_OUTPUT
          echo "start_time=$(date -u +%Y-%m-%dT%H:%M:%SZ)" >> $GITHUB_OUTPUT

  use-computed-values:
    needs: compute-inputs
    runs-on: ubuntu-latest
    steps:
      - name: Use GitHub API with computed values
        env:
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
        run: |
          const github = require('@actions/github');
          const core = require('@actions/core');

          async function run() {
            const workflows = await github.paginate(github.rest.actions.listWorkflowRuns, {
              owner: process.env.deploy_repo_owner,
              repo: process.env.deploy_repo_name,
              workflow_id: 'deploy_plugin.yml',
              created: `>${{ needs.compute-inputs.outputs.start_time }}`,
            });
            console.log(workflows);
          }

          run();

        and the display result was 

 

If your result is the same, then please share your YAML file. Otherwise, please temporarily disable all 3-rd party plugins and let us know if the issue is still reproduced.
