It was very clear to P4 that 'partition' didn't apply to her scenario in
Mission 3 because she was trying to unlock an entire disk and not only a
partition of it.

The previous ones mentioned the tool to be used instead of the goal to
be reached by the user. These ones should be easier to navigate.

People had a hard time spotting it during the user testing.

During the user testing, everybody who looked for it had a hard time
finding it or even gave up.

- Replace TrueCrypt documentation on the command line.
- Adjust LUKS documentation to explain the alternative with VeraCrypt.

This reverts commit c707d4f1.

I'll write the documentation without auto-mounting until we have a
decision on #15628.

Merge remote-tracking branch 'segfault/bugfix/15636-screen-locker-unicode' into stable (Fix-committed: #15636)

Merge remote-tracking branch 'segfault/feature/14481-TCRYPT-support-beta' into feature/14481-TCRYPT-support-beta

The /etc/xdg/gnome-mimeapps.list is created (and overwritten)
by chroot_local_hooks/10-tbb, so we append the required line in a hook.

Merge branch 'feature/15575-open-doc-instead-of-getting-started' into stable (Fix-committed: #15575)

The "Getting started" page had a 'Found a bug?' heading but the "Documentation"
page has no such thing.

The changed string is not translatable so all languages get the English version.

- /getting_started is very old and needs a serious lifting.

- During the user testing of the Additional Software beta, 3 out of 5
  participants ended up on this page. None of them read it. 2 used it to reach
  /doc which is what they were looking for. 1 got lost and ended up on /design.
