[DigitalTwins] Refactor tests to use Test Proxy (#26545)

Tests for "azure-digitaltwins-core" were converted to use Test Proxy.

- Refactored to use pytest fixtures for test prep.
- Updated ci.yml and tests.yml to indicate Test Proxy usage.
- Regenerated recordings using updated tests and deleted old vcrpy
  recordings.
- Added a test-resources.bicep file for live testing.
- Added a sleep for two query tests to ensure the service side reflects
  the latest changes.
