Fix example snippet in docs/google/calibration.md

[pavoljuhas]

Describe the issue

Problem: Whilst reviewing #7803 I found that the snippet in calibration.md uses non-existing Engine.get_job method. The method was removed in #2720.

Cirq/docs/google/calibration.md

Lines 41 to 44 in 912a76e

	# If you know the job-id, you can retrieve the calibration that the job used.
	job = engine.get_job("projects/" + PROJECT_ID
	+ "/programs/"+PROGRAM_ID
	+ "/jobs/" + JOB_ID)

Desired Solution: Replace with current API for the same thing or delete altogether. It is better to have no example than a broken one.

Tell us the version of Cirq where this happens

1.7.0.dev at 912a76e

Hi, I’d be happy to work on this and update the documentation to use the current API.

Hi Furkan-Coban, Thank you for your interest. I feel this one would be easier to handle by an internal contributor, because the new example could be also checked with the actual engine server (in addition to mocks in snippets_test.py). Please feel free to pick up some other unassigned (or dormant) issues.

Hi I'd like to take a look!
