…loads (apache#3621) ### Purpose ### This pull request partially addresses issue apache#3404 by changing the download method of single-file dataset downloads to use browser native downloads. Using the browser to handle downloads enables the browser's file download UI, which includes a progress bar when downloading larger files. Previously, we would generate a pre-signed URL for the file via LakeFS API and download it as a Blob. Now, we generate a pre-signed URL for the file via S3 Gateway API, which offers additional flexibility, and click on the URL to trigger browser native download. ### Changes ### - added method to generate pre-signed URL via S3 Gateway API, with additional flexibility to specify file name and type - updated frontend and backend to directly click on a pre-signed URL generated via the new method for single file dataset downloads - removed success and error notifications for single file dataset downloads (the success and error of a file download cannot be obtained when using browser native download) - updated unit tests to verify new download method Changed Files: - file-service/src/main/scala/edu/uci/ics/texera/service/resource/DatasetResource.scala - file-service/src/main/scala/edu/uci/ics/texera/service/util/S3StorageClient.scala - gui/src/app/dashboard/component/user/user-dataset/user-dataset-explorer/dataset-detail.component.ts - gui/src/app/dashboard/service/user/dataset/dataset.service.ts - gui/src/app/dashboard/service/user/download/download.service.spec.ts - gui/src/app/dashboard/service/user/download/download.service.ts
