Creating a GitHub Action Workflow to Update a Lambda Function on Push

The below workflow will work with a Lambda function written in Node. It's set up to run on every push, but could be updated for other actions.

The workflow is also set up to run on the main branch.

on:
  push:
    branches:
      - main
jobs:
  my_job:
    runs-on: ubuntu-latest
    name: Lambda Update Function Code
    steps:
      - name: Install Dependencies
        run: |
          sudo apt-get update
          sudo apt-get install zip
      - name: Checkout
        uses: actions/checkout@v2
      - name: Build
        uses: actions/setup-node@v1
        with:
