[Docs] Clarify storage account documentation in the Azure Logs integration

[zmoog]

The Azure storage account containers documentation in the Azure Logs integration contains conflicting information.
It states:

"The Elastic Agent can use one Storage account container for all integrations" — source

However, it then contradicts this by stating:

"You MUST use a dedicated storage account container for each Azure log type (activity, sign-in, audit logs, and others). DO NOT REUSE the same container name for more than one Azure log type." — source

These statements directly contradict each other.

Action items:

• Resolve the logical contradiction between these statements
• Clarify the storage account requirements in the integration documentation
