Unary operator misused, fails to compile with solidity v8.18

Line 64 in d8b1c63

uint256 twos = -denominator & denominator;

TypeError: Unary operator - cannot be applied to type uint256
  --> @uniswap/v3-core/contracts/libraries/FullMath.sol:64:24:
   |
64 |         uint256 twos = -denominator & denominator;

This line can be safely replaced by the following which is compatible with the newer solidity compilers:

uint256 twos = denominator & (~denominator + 1);
