Fix define Processor typing

[agix]

Processor type used in define doesn't use generic typing.

If you try this:

import Agenda, { Job } from 'agenda'

const agenda = new Agenda()

const run = async function(job: Job<{test: string}>) {
  return Promise.resolve()
}

agenda.define('test', run)

It would raise the following typescript error :

Type '(job: Job<{ test: string; }>) => Promise<void>' is not assignable to type '(job: Job<JobAttributesData>) => Promise<void>'.

Job class use generic type but default to JobAttributesData if none is provided https://github.com/agix/agenda/blob/73184aaa8309e5e89e0cfab766b2cdd6d80e9605/lib/job/index.ts?plain=1#L127

Which is exactly the case in the current Processor definition : https://github.com/agenda/agenda/blob/master/lib/agenda/define.ts#L39-L41

@agix We can merge this after #1358 Where this is an explicit issue

Ok thank you.

JobAttributesData should not be generic typed because is an external resource subject to async manipulations. It should be unknown always.
