feat(content): Add sleepdebt effect

[RoyalFox2140]

Purpose of change

We had no way of using effects to add or remove sleep deprivation, now we do.

Describe the solution

It appears under effect.cpp adding a new "member" for SLEEPDEBT and the relevant json fields happen there, and under character_turn.cpp is the part that hooks into mod_sleep_deprivation to cause the relevant effect to change a players stats.

I don't know the underlying code, this was reworked from the thirst effect and modified to work for sleep.

Describe alternatives you've considered

Testing

I loaded one of my old worlds from 0.4 stable and this change had no related bugs. I have successfully tested it using a spell effect from my mod. You can add the json field "sleepdebt_min": [ -100 ] to any effect you want on testing.

Additional context

Here's some screenshots.

We need to update all effects documentation. That is out of scope right now.

Checklist

If this is a C++ PR that modifies JSON loading or behavior:

• Document the changes in the appropriate location in the doc/ folder.

  {
    "type": "effect_type",
    "id": "contacts",
    "name": [ "Contact Lenses" ],
    "desc": [ "You are wearing contact lenses." ],
    "apply_message": "You can see more clearly.",
    "remove_message": "Your vision starts to blur.",
    "rating": "good",
    "base_mods": {
      "sleepdebt_min": [ -100 ]
    }
  },

1. added sleepdebt_min to contact lenses.
2. debug-added sleep_deprived 100.
3. wore contact lenses.
4. sleep_deprived is gone.

code is mostly Copy-Paste from working ones so i think it's good to go.
also fixed CI not labelling docs properly.
