• I have read the note above about PRs contributing or fixing extensions
• I have tried reaching out to the extension maintainers about publishing this extension to Open VSX (if not, please create an issue in the extension's repo using this template) -> See Publish vscode-azurestorage to Open VSX microsoft/vscode-azurestorage#1460
• This extension has an OSI-approved OSS license (we don't accept proprietary extensions in this repository) -> Yes, MIT https://github.com/microsoft/vscode-azurestorage/blob/main/LICENSE.md

Description

This PR introduces ms-azuretools.vscode-azurestorage as an auto-published extension.
