user-manual: Fix 'both: so' -> 'both; so' typo

Merge branch 'sp/smart-http-content-type-check'

The smart HTTP clients forgot to verify the content-type that comes

handled properly.

* sp/smart-http-content-type-check:
  http_request: reset "type" strbuf before adding
  t5551: fix expected error output
  Verify Content-Type from smart HTTP servers
user-manual: Fix 'http' -> 'HTTP' typos
