fix: remove masking E2E test failures

[hallvictoria]

Description

Separates the E2E test script into 3 different scripts: functions worker process count & threadpool thread count tests, E2E tests, and deferred bindings tests. All the tests will run but if any test in these 3 workflows fails, the pipeline will fail.

Changed issue and feature request templates to be more usable.

Added extra tests

• Generic binding implicit output with a None return value and no type hint
• Blueprints with blueprint.py in a separate folder
• FWPC and blueprints in a separate folder
• newrelic and PIWD

Popped env variables in tearDown() for fwpc and tptc tests.
