Corrected display name for 'Blob Containers Allowing Public Access'

[rieck-srlabs]

Description

This commit changes the UI description for the Azure rule 'Blob Containers Allowing Public Access'. The UI incorrectly specified that the rule scans Storage Accounts, while it actually scans 'Blob Containers'. Since there are potentially more Blob Containers than Storage Accounts, the reported statistics are incorrect.

Fixes #1608
