Now that it's available as a beta feature (almost) everywhere, we should remove the cookie hack we used for testing the reply tool.
For user who had enabled it, we should enable the beta feature instead, so that the tool doesn't disappear for them when we remove that, and so that they can easily disable it if they wish (https://www.mediawiki.org/wiki/Topic:W5dip3pxqfudyutx).

[mediawiki/extensions/DiscussionTools@master] Migrate cookie hack users to beta feature
Does the cookie hack also enable sub-features that are marked as "unavailable" on a specific wiki (none at the moment, but could happen again when we deploy new features)?
Yes, but I think we should only use the URL hack ?dtenable=1 for this.
If we really want to allow users to use "unavailable" features in the long term, then I think we should allow doing it with hidden preferences.
