[BUG] Error when creating repository in GCS bucket

[shashankdk]

Description

I encountered an error when creating a backup repository in a GCS bucket.

Steps to Reproduce:

1. Run the following SQL command:
   CREATE REPOSITORY test_repo WITH BROKER ON LOCATION "s3a://starrocks_poc_1/backup" PROPERTIES( "fs.s3a.access.key" = "XXXX", "fs.s3a.secret.key" = "R+YYY", "fs.s3a.endpoint" = "storage.googleapis.com" );

Error Observed:- ''' ERROR 5064 (42000): Failed to create repository: failed to list remote path: s3a://starrocks_poc_1/__starrocks_repository_test_repo/__repo_info. msg: java.lang.IllegalArgumentException: bucket is null/empty '''

Expected Behavior
The repository should be created successfully in the specified GCS bucket.

Environment:
Application: Docker starrocks/allin1-ubuntu
Docker command used : docker run -p 9030:9030 -p 8030:8030 -p 8040:8040 -itd --name quickstart starrocks/allin1-ubuntu

Additional Info:- The access key, secret key, and bucket name are correct, as I have successfully used these credentials to run docker-compose up with starrocks-fe and starrocks-cn configured to use shared storage on GCS.
