- Fix `StreamlinkOptions._set_http_disable_dh()`, remove the override of
  the old `urllib3.util._ssl.DEFAULT_CIPHERS` list and instead add
  `streamlink.plugin.api.http_session.TLSNoDHAdapter` which reads
  the ciphers returned by Python's default SSLContext, adds `:!DH` to
  the updated ciphers list, and finally replaces the HTTP session's
  `https://` adapter
- Use `urllib3.util.create_urllib3_context()` for creating `SSLContext`
  objects in custom `HTTPAdapter`s
