Handle case when triggered event is a manual workflow_dispatch

[sakethsomaraju]

Fix #94 and #91

Added support to perform "Image Deploy" incase of manual_dispatch github event.

Thanks a lot for taking this up, highly appreciate it 👏
Have we tried out new changes manually? If not, could we do that, and add the result to the PR description?
You could point to this deploy-action branch in the GitHub workflow by specifying the deploy action reference, ex: uses: astronomer/deploy-action@fix/94

Apart from that, I left some minor comments to keep things clean.

Can we reuse these variables for the rest of the logic in this step?

Thanks for taking time to review. :-) Addressed.

nit: could we club both the if clause (this and the one below) into a single clause to avoid code repetition :)

TESTING

Tested with following workflow

name: Personal Astronomer CI - Deploy
on:
  push:
    branches:
      - main
  workflow_dispatch:

env:
  ## Sets Deployment API credentials as environment variables
  ASTRO_API_TOKEN: ${{ secrets.ASTRO_API_TOKEN }}
  WORKSPACE: "clilt7vco00a601kk5fz65ob1"  
  DEPLOYMENT_ID: "cm3spbuo00nt301ni2wggd49b" 

jobs:
  build:
    runs-on: ubuntu-latest
    steps:
    - name: Deploy to Astro DAGS
      # if: ${{ github.event.inputs.deploy_type == 'DAGS' }}
      uses: astronomer/deploy-action@address-review-comments
      with:
        deployment-id: ${{ env.DEPLOYMENT_ID }}
        workspace: ${{ env.WORKSPACE }}
        force: true
        checkout: true

Both Manual trigger and CI trigger were success.
