Description
if a user passes an empty list for the --client-signing-algorithms option, the pointer on https://github.com/sigstore/rekor/blob/main/pkg/api/api.go#L151 will not be nil but should revert to the default setting (since no supported algorithms is nonsensical).
Also fix
which shouldn't be a pointer
