TS: Custom input names for actions

[lolopinto]

this makes it so that if we have 2 create or edit actions, they work

  actions: Action[] = [
    {
      operation: ActionOperation.Create,
      fields: createFields,
      // when all 3 presented, things are fine
      actionName: "UserCreateRequesterAction",
      graphQLName: "userCreateRequester",
      inputName: "UserCreateRequesterInput",
    },
    {
      operation: ActionOperation.Create,
      fields: createFields,
      actionName: "UserCreateVolunteerAction",
      graphQLName: "userCreateVolunteer",
      inputName: "UserCreateVolunteerInput",
    },
  ];

we still need a lot of work to support other types e.g. add/remove edges

still need better default behavior when all 3 custom fields aren't provided

still need better to fix inconsistency in naming conventions of input names e.g. default is CreateUserAction for action name but UserCreateInput for input names. The latter is fine for graphql but dubious for ents

Also, this stems from inconsistency in default behavior e.g. CreateUserAction and 'userCreate`
