Revert "Show hidden files and folders last"

This reverts commit 996e430b62075c5b69571f141456dbe5f2956679.

The accompanying feature to make the behavior configurable and disable
it by default was reverted in 21.08, so we need to revert the feature
itself as well and only ship it in 21.12, to avoid changing people's
setting back and forth, which is often not well-received.
