Summary

Remove the returns (bool) from the mint function because, it always returns true and is not necessary.

Vulnerability Details

Remove returns(bool) from the below function =>
function mint(address _to, uint256 _amount) external onlyOwner returns (bool) {
if (_to == address(0)) {
revert DecentralizedStableCoin__NotZeroAddress();
}
if (_amount <= 0) {
revert DecentralizedStableCoin__MustBeMoreThanZero();
}
_mint(_to, _amount);
return true;
}

Impact

The return value is not necessary and removing it will save some gas. And, it will also make the code cleaner and easier to read as it removes an unnecessary line of code.
