Use 2512 SMD resistors in place of strain gauges (#104)
As suggested in https://github.com/scottbez1/smartknob/issues/24#issuecomment-1073540944 and inspired by https://github.com/IvDm/Z-probe-on-smd-resistors-2512, this adds 4x 330 ohm 2512 SMD resistors to the back to act as strain gauges, rather than requiring discrete strain gauges to be glued and wired up.

Also applies a few changes I accidentally had pending locally:
- Custom footprints for the 2 3.3v LDO options to clarify the pinout options

- some BOM note updates

Fixes #24
Closes #33

Migrate to KiCad 6 (#96)
- Updated view_base and view_screen KiCad projects to v6 files
  - Updated footprints to v6 versions
  - Fixed all DRC errors and most warnings
- Updated CI
  - Run on Ubuntu 22.04 runner
  - Updated KiBot and KiKit versions
  - Use KiBot for 3d rendering now instead of custom scripts
  - Switched to using KiCad text variables for replacement rather than raw text find&replace
- Misc design updates
  - Exposed bottom-side thermal pad underneath TMC6300 to make it easier to possibly hand-solder
  - Separated GND and GNDA nets, replaced connection with a net-tie, and updated corresponding copper fills around HX711

e2076d2eda Remove paste from USB-C pads
USB-C connector will be soldered separately from main top reflow, since it hangs below the board.
