LUKS decryption mistype recovery instructions

These are the decryption instructions for if you mistype your passphrase (and end up in GRUB rescue mode) when logging in to a LUKS encrypted Linux installation.

Tested on Manjaro Linux.

grub rescue> cryptomount (hd0,gpt2) # mount the encrypted partition
Attempting to decrypt master key..
Enter passphrase for hd0,gpt2 (<disk uuid>): # Enter your encryption password

grub rescue> insmod normal
grub rescue> normal # After this command, system should boot as per normal
