Add github actions for deploying AWS ECS envs

[willscripted]

Create github actions for building and deploying LAMP-dashboard

Manual Actions:

• Deploy SHA - Allows an authorized user to build and deploy an arbitrary git sha (long format) to staging or other future testing environments (note, cannot be used to deploy to production).
• Deploy Tag - Allows an authorized user to deploy a docker container to any configured environment (currently only stg and prod. Note that the input for this job is the DOCKER tag, not the git tag. Likely, the docker tags will be in the form of master, sha-somelongformatgitsha, or gittag (eg. 2024.5.9 as is the preferred format in this repository)

Automatic Actions:

• On Branch Update (master) - Runs when a pull request is merged into master or when someone pushes a commit directly to master. The action will build a docker image, push it to the github registry with the docker tag master, and deploy that image to the staging environment (stg) using the image's checksum digest.
• On Pull Request Update - Builds the docker image without publishing it to the github container registry. Some notes here:
  • This action checks the validity of a pull request, it does not publish anything to the registry
  • The only check at the moment is that the image builds successfully. It does not check that the image can be booted.
  • The sha that is built is the sha of the invisible merge commit, not the HEAD of the branch. This could be a source of dependencies if it "works on my machine"
  • Because this action listens to the edited webhook type (among others), it will be triggered each time the base branch is updated. If there are lots of open pull requests, this could mean an unhelpful amount of rebuilds when master is updated.
• On Tag - Runs when a new tag is pushed to the repository. It is the same as the "On Branch Update (master)" job except that the resulting docker tag will be the name of the git tag pushed (eg git tag of 2024.5.9 will create a docker tag of 2024.5.9)

Tasks or Callable Workflows:

These two workflows should not be called directly, but instead called by an "On "-style workflow. No need to do anything here, just wanted to explain all the new files. The "Build" task builds the docker image. The "Deploy" task deploys the docker task to the Digital Psych AWS ECS environment(s).

@MattMatt27 -- should be all set 🥳

Mostly informative questions for my own education!

Sounds good -- I'll respond to comments and we discuss and cherry-pick the changes that should be made tomorrow 👍
