flyte Implement GetProject endpoint in FlyteAdmin

Tracking issue

Closes #4317

Why are the changes needed?

We have several services and operators that fetch single Project objects from flyteadmin. This new endpoint will save some filtering by only fetching the one we need instead of fetching a List of Projects (the endpoint available today)

Note: This replaces #4316 (diverged too much from main)
