Remove network-uri-188.8.131.52 patch
In !73 I mistakenly believed that `network-uri-184.108.40.206` needed to be patched. However, I was mistaken: only `network-uri-220.127.116.11`, not `18.104.22.168`, needs to be patched to build against HEAD. The reason is because the error message that you would get when building `22.214.171.124` against HEAD only occurs when `TemplateHaskellQuotes` is enabled (see ghc@82023524). On the other hand, `network-uri-126.96.36.199` no longer enables `TemplateHaskellQuotes` on recent GHCs, making the patch that I committed wholly unnecessary.
