HOTFIX - Loosely pin configure-aws-credentials to v4

[coreycarvalho]

Description

#2229

This PR serves two purposes:

1. Loosely pin the Github action configure-aws-credentials to v4 instead of hard pinning it to 4.0.2.
2. Getting notification API reconciled post code freeze.

This PR is being set to a minor version update to make sure that all of the changes that were merged during the holiday code freeze are packaged nicely into a minor version bump. Following the merging of this PR, @cris-oddball will organize and update release notes to accurately reflect the set of changes going out to production.

How Has This Been Tested?

The dev deploy being successful is a sufficient test.
