Description
### Search before asking
- [X] I searched in the [issues](https://github.com/apache/paimon/issues) and found nothing similar.
### Paimon version
paimon 0.9.0
### Compute Engine
starrocks 3.2.12/3.3.7
### Minimal reproduce step
1. Building Paimon Table Based on AWS S3 Compatibility Object Storage, Paimon Catalog DDL is as follows:

2. Create Paimon Catalog in Starrocks:

3. Querying Paimon Catalog Data Table in Starrocks

4. Query failed with the following error message

### Anything else?
1. Paimon table storage uses AWS S3 compatible object storage,and it has been confirmed that AK/SK is correct
2. According to current testing, starrocks 3.1.15 + Paimon 0.9.0 does not have this issue
3. Using the same set of AWS S3 compatible object storage, Starrocks can query its own internal table (using this object storage) normally, but when Starrocks queries the Paimon table (also stored using this object storage) through the Paimon catalog, it will fail

Research direction
Start with the S3 access failure in be/src/connector/hive_connector.cpp:129 and the scan paths named in be/src/exec/pipeline/scan/connector_scan_operator.cpp and fragment_executor.cpp. Compare Paimon catalog reads in StarRocks 3.1.15 with 3.2.12/3.3.7, focusing on the signature mismatch for S3-compatible storage. Done means querying the Paimon table succeeds with the same storage and credentials.
