Update Azure SDK versions

[patst]

This update updates the azure SDKs:

• upgrade azidentity to v1.3.0
• update azcore to v1.6.1

Especially the azidentity part is interesting, because after merging this WorkloadIdentityCredential is available and be used.

This is interesting for authorization inside Azure Kubernetes Service using Workload Identity. See the discussion at grafana/grafana#53645 for details

Thank you for the contribution @patst. I don't think this completely solves the issue mentioned in grafana/grafana#53645 but it will allow us to make use of the DefaultAzureCredential which then solves the problem.
