How to access a bucket using S3:// uri?

From the PR:
https://github.com/datafuselabs/databend/pull/4170/files#diff-dc7428e39de9915b0830549374e55e143995149f2a90303d38e4017d014d2fc2R79-R84

The file_location is s3://databend-external/t_ontime/t_ontime.csv, opendal stat will return Unexpected("s3://databend-external/t_ontime/t_ontime.csv").

Looks we should do a convert:

# s3://example-bucket/path/to/object
http(s)://example-bucket.s3.amazonaws.com/path/to/object
http(s)://s3.amazonaws.com/example-bucket/path/to/object
