This commit adds promotional notice on appearance settings about
translation project if any other locale than English is used. It
allows users to learn and contribute translations to Mastodon.

Step ahead, in this commit one unusual string is added - link to a
guide. By default it refers to Crowdin project itself, but if any of
Mastodon localization teams established their own guide, they can
refer it. Or, if Crowdin supports localized domain for language, it
can also be put there (e.g. https://fr.crowdin.com/...).

Fix #12510

This changes the REST API to return unicode domains in the `acct`
attribute instead of punycode, and to render unicode instead of
punycode on public HTML pages as well.

Fix #7812, fix #12246

Those were used to show a “follow” or “unfollow” button on account grid on
public pages, but that got removed a while ago.

Fix #12619

Fix #12255

Fix #12509
See also #12214

Regression from #12661

* Make BackupService resilient to read timeouts

If an attachment read times out, assume that the resources is
inaccessible and continue the backup without it. This fixes #12280.

* Both errors on one line

* Update config.yml

* Update Gemfile.lock

- Allow batch actions on unreviewed tags
- Hide checkboxes when batch actions aren't available

* Summary: fix slowness due to layout thrashing when reloading a large set of status updates

in order to limit the maximum size of a status in a list view (e.g. the home timeline), so as to avoid having to scroll all the way through an abnormally large status update (see https://github.com/tootsuite/mastodon/pull/8205), the following steps are taken:
•the element containing the status is rendered in the browser
•its height is calculated, to determine if it exceeds the maximum height threshold.
Unfortunately for performance, these steps are carried out in the componentDidMount(/Update) method, which also performs style modifications on the element.  The combination of  height request and style modification during javascript evaluation in the browser leads to layout-thrashing, where the elements are repeatedly re-laid-out (see https://developers.google.com/web/fundamentals/performance/rendering/avoid-large-complex-layouts-and-layout-thrashing & https://developer.mozilla.org/en-US/docs/Mozilla/Firefox/Performance_best_practices_for_Firefox_fe_engineers).
The solution implemented here is to memoize the collapsed state in Redux the first time the status is seen (e.g. when fetched as part of a small batch, to populate the home timeline) , so that on subsequent re-renders, the value can be queried, rather than recalculated.  This strategy is derived from https://github.com/tootsuite/mastodon/pull/4439 & https://github.com/tootsuite/mastodon/pull/4909, and should resolve https://github.com/tootsuite/mastodon/issues/12455.

Andrew Lin (https://github.com/onethreeseven) is thanked for his assistance in root cause analysis and solution brainstorming

* remove getSnapshotBeforeUpdate from status

* remove componentWillUnmount from status

* persist last-intersected status update and restore when ScrollableList is restored

e.g. when navigating from home-timeline to a status conversational  thread and <Back again

* cache currently-viewing status id to avoid calling redux with identical value

* refactor collapse toggle to pass explicit boolean
