* 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. * Update CHANGELOG * fix: ensure transpiler compatibility * fix: fixing var-name-mixedcase * prettier & lint check Signed-off-by: Pascal Marco Caversaccio <pascal.caversaccio@hotmail.ch> Co-authored-by: Hadrien Croubois <hadrien.croubois@gmail.com>
