fix: update car dependency for CARv2 read support (#4085)

4.x adds basic CARv2 read support, so you could `ipfs dag import` a CARv2 with this; also with https://explore.ipld.io/ getting CAR support, this would allow importing and inspection of a CARv2 there.

The breakage was in the return type definition of `CarReader#header()` which I don't believe is touched in js-ipfs, which only cares about `getRoots()` in the header which remains the same.
