[GridGen] button to quickly toggle or remove values

[rafstahelin]

Would be great to apply the same feature of token one-click remove in the grid generator like it is possible to do with lora's for instance

Often find myself editing which sampler or Lora to remove from a long list. Having to highlight and delete, and delete the comma exacerbates the amount of clicks required to setup a grid.

Anyway, maybe not a priority but a happy quality of life improvement
