* replace `immutable` with `constant` for _PERMIT_TYPEHASH
This commit is related to the following issue discussion: https://github.com/OpenZeppelin/contracts-wizard/issues/89#issuecomment-1042391318
Since Solidity version `0.6.12` the `keccak256` of string literals is treated specially and the hash is evaluated at compile time. Since the OpenZeppelin Wizard also uses `constant` for OpenZeppelin's AccessControl's roles declarations, it's good practice to make this consistent.
