This PR adds header
x-middleware-subrequestintotx.restricted_headers_basic, so it's going to be blocked by default. At first, we were considering to not block it by default (as it will disable some features of Next.js) but after it was completely removed from Next.js, i suggest to just block it. If we do not agree on this, i can move it intotx.restricted_headers_extendedwhich will block it from PL2.Fixes: #4051
