Write a `sharness` test that expects failure documenting the issue
raised in #3503. The issue may get resolved in the refactoring of
`ipfs dag get` command to support go-ipld-prime (e.g. #8171). For now
add a `sharness` test that expects failure. We will then flip the
expectation in the success in the rewriting PR to check if #3503 gets
resolved.
