[KEYBOARD] Fix left key code in extended_key_names in several layouts (#7311)

I found this bug while testing random games, the left key didn't work.
After switching to other keyboard layouts (German, English) the problem
disappeared. There are games (e.g. Doom 3 demo, Tomb Raider 2 demo) that
somehow use this code from extended_key_names to determine which key the
user pressed. It might be a good idea to check other keyboard layouts too,
since I found that table inconsistent across languages.
