Update deploy workflow and Makefile

Why these changes are being introduced:
Deployment of lambda functions requires updating the function code in
addition to pushing the container to ECR.

How this addresses that need:
* Adds update-lambda-function command to the dev_ecr_push workflow
* Updates the Makefile to use a generic name for the update lambda
  function (previously had a copy/pasted name specific to another repo)

Side effects of this change:
* All future pushes to `main` will update the lambda function code
  after pushing the new container

Relevant tickets:
* https://mitlibraries.atlassian.net/browse/ENSY-77
