[BUG] HoldTap in Combos with debug mode active will throw exception when activated

[TomVollerthun1337]

Describe the bug When using a HoldTapKey in a Combo and activating the debug mode, the firmware will crash, display a stacktrace and abort running.

Since the refactoring Add KeyboardKey class to distinguish from internal Keys, internal keys like HoldTapKey don't have a code attribute anymore and trying to access it must fail.

Since kmk/modules/combos.py#L59 (__repr__ - creates string representation, p.e. for debugging) accesses the code attribute of matching keys unconditionally, it results in an AttributeError: 'HoldTapKey' object has no attribute 'code'.

To Reproduce Steps to reproduce the behavior:

• Use the current main branch
• Use this minimal example as main.py:

  
  from kmk.keys import KC
  from kmk.modules.combos import Combos, Chord, Sequence
  from kmk.modules.holdtap import HoldTap
  keyboard = KMKKeyboard()

keyboard.modules.append(HoldTap())

S_A = KC.HT(KC.S, KC.A) T_M = KC.HT(KC.T, KC.M)

combos = Combos() combos.combos = [ Chord((S_A, T_M), KC.HT(KC.PLUS, KC.R)), ] keyboard.modules.append(combos)

from kmk.keys import KC keyboard.keymap = [[S_A, T_M]] keyboard.debug_enabled = True

if name == 'main': keyboard.go()

* Input: Press the two keys that are configured in the combo (hold or tap doesn't matter)
**Expected behavior**
Output should be the result of the combo: PLUS on tap, R on hold

**Debug output**
