bug(fill): confusing error with an invalid local eels resolver path

[danceratopz]

If an error is made in a local path specified in eels_resolution.json such as:

    "London": {
        "path" : "../../execution-specs/src/ethereum/loooondon"
    },

then fill executed with, for example,

uv run fill --fork=London -x -v tests/istanbul/eip1344_chainid/ -m state_test

returns the error message:

It would be helpful to return the underlying error returned by the ethereum-spec-evm-resolver.
