[BUG] Question on usage to ignore PR's from dependabot

### Action config
currently we are using Deploy to Firebase Hosting on PR and we have several repo's that contain the config below. When we receive a pull request from dependabot the action fails due to permissions. How can this config be changed to ignore the action (skip or no run) when the PR is opened by dependabot. Thanks for any input on this...

example:
name: Deploy to Firebase Hosting on PR
'on': pull_request
jobs:
build_and_preview:
if: '${{ github.event.pull_request.head.repo.full_name == github.repository }}'
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v2
- run: yarn && yarn build
- uses: FirebaseExtended/action-hosting-deploy@v0
with:
repoToken: '${{ secrets.GITHUB_TOKEN }}'
firebaseServiceAccount: '${{ secrets.FIREBASE_SERVICE_ACCOUNT_BLUI_REACT_SHOWCASE }}'
expires: 2d
projectId: blui-react-showcase
