🎉 Support for access block fields in prefect.yaml templating

You can now access fields on blocks used in your prefect.yaml files. This enables you to use values stored in blocks to provide dynamic configuration for attributes like your work_pool_name and job_variables.

Here's what it looks like in action:

deployments:
- name: test
  version: 0.1
  tags: []
  description: "Example flow"
  schedule: {}
  entrypoint: "flow.py:example_flow"
  parameters: {}
  work_pool:
    name: "{{ prefect.blocks.json.default-config.value.work_pool }}"
    work_queue: "{{ prefect.blocks.json.default-config.value.work_queue }}"

In the above example, we use fields from a JSON block to configure which work pool and queue we deploy our flow to. We can update where our flow is deployed to by updating the referenced block without needing to change our prefect.yaml at all!

Many thanks to @bjarneschroeder for contributing this functionality! Check out this PR for implementation details: #10938
