fix: Allow the remove operation to have a value

* When removing an entry from an array, then value is required, so making value optional.

Eg:
{
   operation: "remove",
   field: "/member/-",
   value: "someEntry",
}

vs

{
   operation: "remove",
   field: "member"
}

Which removes the member field entirely
