Automated compatible models list for task guides
# What does this PR do?

This PR adds a script that aggregates model architectures compatible with a task illustrated in a task guide and adds a list of links to them in a <Tip> in the guide. This serves several purposes: 
1. Reinforces the idea that task guides are applicable to more than one model architecture. 
2. Improves discoverability of models. 
3. Serves as the first step to improve navigation between task guides and model docs.
