Bump `azure-mgmt-eventgrid` pin to `~=10.2.0`

[janjagusch]

This project currently pins azure-mgmt-eventgrid to a particular beta release.

azure-cli/src/azure-cli/setup.py

Line 85 in cd8c932

'azure-mgmt-eventgrid==10.2.0b2',

However, a stable release has long been available:

• https://pypi.org/project/azure-mgmt-eventgrid/10.2.0/
• https://pypi.org/project/azure-mgmt-eventgrid/10.4.0/

Unfortunately, It seems there was a breaking change between azure-mgmt-eventgrid==10.2.0b2 and azure-mgmt-eventgrid==10.2.0. That's not ideal.

ImportError: cannot import name 'ResourceSku' from 'azure.mgmt.eventgrid.models' (/home/runner/work/azure-cli/azure-cli/env/lib/python3.12/site-packages/azure/mgmt/eventgrid/models/__init__.py). Did you mean: 'Resource'?
