Broken uploads on Conda with S3 storage

[ChGen]

Broken upload operations for conda repositories with S3 storage. Looks like filesystem storage isn't affected. Could be reproduced with local instance of artipie with local minIO S3 server. It works mostly for the first package upload, subsequent uploads are getting struck in .upload folder.

Also:

• amazon s3 client should be updated to the new version.
• asto-core should be buildable & testable with jdk21
• more integration/smoke tests with s3 storage servers required

It didn't complain about anything in case of success scenario

If I tried to restart and re-login in to the artipie server between the uploads, it is not hanging, but it is throwing like this
