Show retries for HTTP status code errors (#13897)

Using a companion change in the middleware
(TrueLayer/reqwest-middleware#235, forked&tagged
pending review), we can check and show retries for HTTP status core
errors, to consistently report retries again.

We fix two cases:
* Show retries for status code errors for cache client requests
* Show retries for status code errors for Python download requests

Not handled:
* Show previous retries when a distribution download fails mid-streaming
* Perform retries when a distribution download fails mid-streaming
* Show previous retries when a Python download fails mid-streaming
* Perform retries when a Python download fails mid-streaming
