It has been removed in openzeppelin v5 and most likely not coming back. You can either downgrade OZ version to 4.x, which is not recommended since a lot of patches have been merged since then fixing various vulnurabilities, or you can replace counter with something else, in most cases a single variable will do the trick. For more details I'll advise to check out the PR which removed Counters.sol from OZ codebase - it contains the reasoning behind this move and different strategies how one can move on without it
