fix: #117 handling noncount nouns / no plural forms by configuring operation names

[mwillbanks]

Provide a way to override operation names to handle edge cases where the resource name is not the actual operation or the operations were customized

useDataProvider({
  operationNames: {
    RESOURCE_NAME: {
      create: "myCreateOperation",
      update: "myUpdateOperation",
      delete: "myDeleteOperation",
      one: "myOneOperation",
      many: "myManyOperation"
    }
  }
});

hi @mwillbanks sorry for the late response, i wanted to merge this, but i saw that a similar change was already introduced, at least for mutations

i will rehaul all data provider options that are specific for resources soon here https://github.com/panter/ra-data-prisma/issues/128, so i will also check if your usecase is covered
