Add hint for custom k_diffusion scheduler

    "Multiplier for extra networks": "When adding extra network such as Hypernetwork or Lora to prompt, use this multiplier for it.",

    "Discard weights with matching name": "Regular expression; if weights's name matches it, the weights is not written to the resulting checkpoint. Use ^model_ema to discard EMA weights.",

    "Extra networks tab order": "Comma-separated list of tab names; tabs listed here will appear in the extra networks UI first and in order lsited.",

    "Negative Guidance minimum sigma": "Skip negative prompt for steps where image is already mostly denoised; the higher this value, the more skips there will be; provides increased performance in exchange for minor quality reduction."

    "Negative Guidance minimum sigma": "Skip negative prompt for steps where image is already mostly denoised; the higher this value, the more skips there will be; provides increased performance in exchange for minor quality reduction.",

    "Custom KDiffusion Scheduler": "Custom noise scheduler to use for KDiffusion. See https://arxiv.org/abs/2206.00364",

    "sigma min": "the minimum noise strength for the scheduler. Set to 0 to use the same value which 'xxx karras' samplers use.",

    "sigma max": "the maximum noise strength for the scheduler. Set to 0 to use the same value which 'xxx karras' samplers use.",

    "rho": "higher will make a more steep noise scheduler (decrease faster). default for karras is 7.0, for polyexponential is 1.0"
