chore: add health cicd

[gweiying]

Context

How did you solve the problem?

This PR adds the following deployment actions to our GitHub Actions:

• Deploys GoGov web application to health-staging Elastic Beanstalk
• Deploys GoGov web application to health-production Elastic Beanstalk
• Deploys GoGov Serverless migration functions to health-* Lambda
• Deploys GoGov Serverless migration functions to edu-* Lambda

This PR uses the edu asset variant in the CI/CD pipeline for building the health environment. We will replace the asset variant in a later PR when the health assets are ready.

Tests

What tests should be run to confirm functionality?

Push branch to edge

• Verify that all deployment actions occur correctly via GitHub Actions console
• Verify on Elastic Beanstalk console that EB staging applications have been redeployed
• Verify on Lambda console that Lambda staging applications have been redeployed

Deploy Notes

Notes regarding deployment of the contained body of work. These should note any
new dependencies, new scripts, etc.

1. This PR uses the edu asset variant in the CI/CD pipeline for building the health environment. We will replace the asset variant in a later PR when the health assets are ready.

2. health-production and edu-production Lambda functions have not been set up yet. If the branch is pushed to production, the Lambda functions will be generated from scratch, and we will need to log in to configure the network configurations.
