fix(consume): fixes for index generation with ethereum/tests

[danceratopz]

🗒️ Description

Two small fixes for index generation with ethereum/tests:

1. Allow index generation at any level of the directory structure by removing the relative path prefixes to fixtures that aren't supported. Only check their names (they have unique names). This allows uv run genindex -i ethereum/tests/BlockchainTests/some/path. Note, we can't load ethereum/tests state tests yet, only blockchain tests.
2. Include the ethereum/tests info_[generatedTestHashasfixture_hash. This is not ideal, due to the info field name mismatch and as EEST fixture hashes are "0x" prefixed and ethereum/tests hashes aren't. But, it will at least allow verification that individual fixture files are up-to-date (this will not affect index.json regeneration, as this depends entirely on hasher`).
