Closes #47913

See merge request gitlab-org/gitlab-ce!21413

Saved Wiki content goes through the GitalyClient::WikiService, which calls
StringIO#set_encoding on the input stream. The problem is that this call
mutates the encoding of the given string object to ASCII-88BIT, which
causes problems for models expecting the data to still be in UTF-8.

Freezing the input disables this behavior:
