Automate Package Dependency Updates

[seantleonard]

As a follow up to the improvements from the PR addressing #948 and Ani's suggestion, we could add automated dependency upgrades (minor/patch versions to start with).

We can use GitHub's Dependabot if compatible with our private NuGet feed:
https://docs.github.com/en/code-security/dependabot/dependabot-version-updates/about-dependabot-version-updates

Local tooling possibilities:

This seems to become a need every patch tuesday because the upstream feed needs to be updated with latest dependencies to not fail nuget restore.
