Subject: [PATCH] docs: fix linkcheck
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When running with the linkcheck builder,
app.builder.default_translator_class is None, making us throw an
exception and give up.

We don't need the bootstrap extension in this case, so just do nothing
instead.
