Gearbox lock

Editorial Gearbox Lock mod from the author Lempaa.
A small script that allows you to disable the automatic gear change of the gearbox

Changes:
-Translation into Russian
-For more convenient use of the script, the key has been changed to "4"
-The script has been edited, now the checkpoint is blocked not on all your vehicles, but only on the one you were in
-Minor edits
The log is clear. During testing, no conflicts with other scripts were noticed.
