fix(api): change slots used to calibrate belts

[pmoegenburg]

Overview

Currently, we use deck slots 12, 3, and 10 to calibrate the x and y gantry belts. With 12 being the designated garbage slot, it would be more user-friendly to not use this slot. The same calibration results (attitude matrix with same orientation) can be achieved using deck slots 1, 10, and 3.

Test Plan

Below are the belt calibration results achieved using these two sets of deck slots. The calibrate_belts api method was used.

Slots (12, 3, 10) Belt Calibration Attitude Matrix:
[[0.9979, -0.0001, 0.0], [0.0007, 0.9984, 0.0], [0.0, 0.0, 1.0]]

Slots (1, 10, 3) Belt Calibration Attitude Matrix:
[[0.9983, -0.0, 0.0], [0.0007, 0.9985, 0.0], [0.0, 0.0, 1.0]]

Seems like a good idea but please put a more in-depth description in the PR description and eventual commit message.
