Azure CLI <= 2.87.0 may display extension version as `unknown` due to extension metadata parsing optimization

[necusjz]

Description

Azure CLI versions <= 2.87.0 may incorrectly display an installed extension version as unknown instead of the actual version.

This issue is fixed in Azure CLI 2.88.0.

Root cause

Azure CLI recently optimized the extension metadata parsing logic to improve how package metadata is processed.

Due to this change, some newly published extension packages may not be parsed correctly by Azure CLI versions <= 2.87.0, causing the extension name and version information to be unavailable.
