Create checks for unit tests in FHIR converter

[austin-hall-skylight]

Description

Now that our custom FHIR converter code has been moved into the Skylight FHIR Converter repo, we need to create a workflow to run the tests.

What needs to be done

Create a workflow with steps to run unit tests for the dotnet tests as well as the liquid template tests.

Why it needs to be done

This needs to be done so we can have make sure that we don't merge code with bugs.

Acceptance Criteria

• [x] Dotnet unit tests run on creation of a PR.
• [ ] Liquid template tests run on creation of a PR.

The dotnet unit tests already run on creation of a PR. Which ones are the liquid template tests?

Ah, I see now that this is blocked on those tests coming into existence 😅
