CKV2_AZURE_21 code sample is incorrect and means the suggested fix is not clear

https://github.com/hlxsites/prisma-cloud-docs/blob/84b15ece336e7f93023adda6a2fb8b6660389f20/docs/en/enterprise-edition/policy-reference/azure-policies/azure-logging-policies/ensure-storage-logging-is-enabled-for-blob-service-for-read-requests.adoc?plain=1#L88-L93

- The `azurerm_storage_container` resource references itself.
- The container name looks like a blob name

As it's not clear what the intention of this snippet is I can't suggest a fix for it.

Also
- There are stray characters at the end of the example block on https://github.com/hlxsites/prisma-cloud-docs/blob/84b15ece336e7f93023adda6a2fb8b6660389f20/docs/en/enterprise-edition/policy-reference/azure-policies/azure-logging-policies/ensure-storage-logging-is-enabled-for-blob-service-for-read-requests.adoc?plain=1#L52-L53
- There is an extra `{` at the start of the snippet, and an extra `}` after the `",` on https://github.com/hlxsites/prisma-cloud-docs/blob/84b15ece336e7f93023adda6a2fb8b6660389f20/docs/en/enterprise-edition/policy-reference/azure-policies/azure-logging-policies/ensure-storage-logging-is-enabled-for-blob-service-for-read-requests.adoc?plain=1#L96-L97

Start in the linked AsciiDoc file, especially the examples around lines 52-53, 88-93, and 96-97, and read the surrounding policy text to determine the intended Terraform and Azure configuration. Done means the example no longer contains stray or mismatched braces, avoids the self-reference, and clearly expresses the intended fix.
