azureml.data.azure_storage_datastore upload_files() does not set mime type when uploading to storage container static website.

Uploading files to the designated $web container using the python sdk upload_files() command to a blob storage static website does not correctly set the mime type to "text/html" for files with .html suffixes. See https://docs.microsoft.com/en-us/python/api/azureml-core/azureml.data.azure_storage_datastore.azureblobdatastore?view=azure-ml-py#upload-src-dir--target-path-none--overwrite-false--show-progress-true-

This should be done automatically on upload as mentioned in https://docs.microsoft.com/en-us/azure/storage/blobs/storage-blob-static-website-how-to?tabs=azure-cli

The work-around is to manually set content type in the Storage Explorer, to programmatically use the Python SDK set_http_headers(content_settings=None, **kwargs)

從 azureblobdatastore 的 Python SDK upload_files() 入口點開始，將其行為與 issue 中連結的靜態網站文件進行比較。檢查 set_http_headers() workaround，並驗證將 .html 檔案上傳到 $web 容器後，content type 是否為 text/html。
