Tweak allowable_closedloop_error value

[GLDuval]

This PR fixes the issue where the tracks would still move after the tracks stopped receiving an input.

This is not the right fix, this will allow the tracks to freely spin when no command is sent, the core issue here is the I parameter of the PID being too large, we could limit it further and/or lower the gain but for the momment, I simplified the system to just use a P controller, we need to tune the PID right in order to fix it properly
