Suggestion to Add Documentation for S3 Integration

[baptvit]

Description of the improvement

While exploring the repository, I noticed examples of integrations with S3 through Minio. However, I could not find comprehensive documentation explaining how to configure S3 integration. If such documentation does not exist, I would like to suggest creating a guide or documentation to make it easier for users to set up and configure S3 storage, as well as other potential storage solutions.

Expected behavior

Provide a clear and detailed documentation or guide on integrating with S3 storage. This guide could include:

Step-by-step instructions for configuring S3 with Minio (or other compatible tools).

hey @baptvit you may want to check out the updated doc under https://github.com/apache/hudi-rs/tree/main/demo , see if things are clearer? Feel free to also submit PR to improve it.
