Fix solc wrapper to check both nested and direct binary paths

The solc-select tool stores binaries differently on different systems:
- MacOS/local: artifacts/solc-X.Y.Z/solc-X.Y.Z (nested structure)
- Linux/CI: artifacts/solc-X.Y.Z (binary directly)

Updated the wrapper to check both patterns in both VIRTUAL_ENV and HOME locations.
