Display tip to check keyboard layout after 3 tries to unlock Persistent Storage
Idea by @emmapeel. People on tails-bugs@ also frequently have problems typing their passphrase. They might need help to have the correct keyboard layout.
After a user typed a wrong passphrase 3 times, we could display a tip to check the keyboard layout and show the password to make sure that it's being typed correctly.
#5501 would help as well.
