Test Subcontainer Validation

Documentation for tests/prague/eip7692_eof_v1/eip7620_eof_create/test_subcontainer_validation.py.

Generate fixtures for these test cases for Prague with:

Prague only: 

fill -v tests/prague/eip7692_eof_v1/eip7620_eof_create/test_subcontainer_validation.py --fork=Prague --evm-bin=/path/to/evm-tool-dev-version
For all forks up to and including Prague: 
fill -v tests/prague/eip7692_eof_v1/eip7620_eof_create/test_subcontainer_validation.py --until=Prague --evm-bin=/path/to/evm-tool-dev-version
