doc: support multidimensional arrays in type link

Currently, we have at least one multidimensional array
in type signature: see `records` parameter in
https://nodejs.org/api/dns.html#dns_dns_resolvetxt_hostname_callback

Our type parser does not linkify these signatures properly.
This PR tries to fix this.
