Suggesting updates on the doc of AccessControl._grantRole and AccessControl._revokeRole

[DocCon-team]

Hi,

The AccessControl._grantRole function might emit a RoleGranted event, which is not documented in its doc.

openzeppelin-contracts/contracts/access/AccessControl.sol

Line 220 in fcf35e5

emit RoleGranted(role, account, _msgSender());

Similarly, the AccessControl._revokeRole function might emit a RoleRevoked event, which is not documented in its doc either.

openzeppelin-contracts/contracts/access/AccessControl.sol

Line 232 in fcf35e5

emit RoleRevoked(role, account, _msgSender());

A potential fix could be adding "Might emit a {RoleGranted} event" to the doc of AccessControl._grantRole, and adding a "Might emit {RoleRevoked} event" to the doc of AccessControl._revokeRole, respectively.

Could you please check it?

Thanks.
