Subject: [PATCH] http: fix validation of "Link" header

Updated regex for "Link" header validation to better match the
specification in RFC 8288 section 3. Does not check for valid URI
format but handles the rest of the header more permissively than
before. Alternative to another outstanding PR that disables validation
entirely.

Fixes: https://github.com/nodejs/node/issues/46453
Refs: https://www.rfc-editor.org/rfc/rfc8288.html#section-3
