Getting empty job variables when using job: Job in worker

[nilsonrossi]

According to the doc, i can define in worker parameters, the variable job: Job, so we can get the Job instance.
However, the job.variables is always empty and i think the error is when pulling the jobs:

pyzeebe/pyzeebe/worker/job_poller.py

Lines 54 to 61 in 7700d0a

	jobs = self.zeebe_adapter.activate_jobs(
	task_type=self.task.type,
	worker=self.worker_name,
	timeout=self.task.config.timeout_ms,
	max_jobs_to_activate=self.calculate_max_jobs_to_activate(),
	variables_to_fetch=self.task.config.variables_to_fetch,
	request_timeout=self.request_timeout,
	)

The variable self.task.config.variables_to_fetch in this case is ['job']. This mean that, if there isn't a job variable in the instance variables, the worker will receive a Job with an empty variables.

How to reproduce:

• Just create a worker with job: Job as parameter, and print(job.variables) inside the function.
• Run a new process passing some data in variables.

@worker.task(task_type="task_1")
def task_1(job: Job):
    print(job.variables)
    return {}

If i run a new process with {"var1": "value"} variable, the worker should print exact the same variables.Sorr
Sorry about the English if i made some mistakes.
