Update to distribution 3.x.x: Fix S3 Virtual Hosted Style incompatibility

[yourdearconner]

Currently, Harbor relies on distribution 2.x.x, which does not support S3 backend storage via Virtual Hosted Style. Many S3 providers or self-hosted S3-compatible storage solutions (such as Alibaba OSS, self-hosted MinIO, etc.) only support the Virtual Hosted Style access method. Using distribution 2.x.x leads to incompatibility and failure to use S3 storage properly in these scenarios.

The upstream distribution project has addressed this issue in version 3.x.x. See the relevant distribution issue: distribution/distribution#4452.

Suggestion:
Please consider upgrading Harbor’s distribution dependency to 3.x.x or above in order to support S3 Virtual Hosted Style.

Reference:

• Support Virtual Hosted Style s3 complicated storage servers. distribution/distribution#4452 Support Virtual Hosted Style s3 complicated storage servers.

Thank you!
