censors: simply use `revlog.reading` to keep things open dring rewrite

We have a dedicated context now, we can simply use it.

In practice, we cannot "simply" use it, as `finddeltainfo` still requires the
file pointer to be passed explicitly. We will keep the old context manager open
for a small bit until we get rid of it in a future changeset.
