fix: correct typos in test function names and variables in nmt_wrappe…

…r_test.go (#4207)

- Renamed `TestErasureNamespacedMerkleTreePushErrors` to
`TestErasuredNamespacedMerkleTreePushErrors` for consistency.
- Fixed variable name `sqaureSize` to `squareSize`.

These changes enhance code readability and maintainability.
