Print full error message for GenericError

[weiji14]

What I am changing

• Make BareRedirect, Server, Client, Reqwest error message more informative

How I did it

• Change format!("{err:#?}") to err.to_string()

How you can test it

• Run uv run maturin develop -m obstore/Cargo.toml, and then try opening some file object that requires setting AWS_REGION or other environment variables

  import obstore as obs
  
  store = obs.store.from_url(url="s3://<bucket-name>")
  response = obs.get(
      store=store, path="abcdefghijklmnopqrs/1234567890.jpeg"
  )

• Should get full error messages like:

  GenericError: Generic S3 error: Received redirect without LOCATION, this normally indicates an incorrectly configured region
  GenericError: Generic S3 error: Error after 10 retries in 12.3456789s, max_retries:10, retry_timeout:180s, source:error sending request for url (http://169.254.169.254/latest/api/token)

Let me know if you'd like some unit tests for this (and where to add them).

This seems fine. I'm not sure if we need tests for this, or, if we do, what the best way to have tests is.
