Register MediaInfo talk namespace

As noticed in the comment T159709#3200587 talk page link currently
leads to the page in the main namespace.
For now always register talk namespace for MediaInfo pages. If there
is a need to allow disabling this namespace, this should be done
separately after planning how to actually do this.
