Request retries respect response

[Drvi]

I think we recently increased our usage of CapturedExceptions which broke isrecoverable, which dispatches on exception type and tries to recover exceptions by default.

Without this PR, the following would hang for 15 minutes.

import HTTP
HTTP.retryable(status::Int16) = false

using CloudStore
url = "azure://account/container/file.csv"
ok, host, account, container, blob = CloudStore.parseAzureAccountContainerBlob(url)
store =  CloudStore.Azure.Container(container, account; host)
retry_delays = ExponentialBackOff(n=12, max_delay=180, factor=3.0) # ~ 15 minutes of total delay time
credentials = nothing
CloudStore.get(store, blob; credentials, retry_delays, retries=length(retry_delays), verbose=2) # retries 403

This would also explain https://github.com/RelationalAI/raicode/pull/13231#discussion_r1180219818

Not sure whats up with CI, but I'm getting failures even locally on master

Yeah, CI is broken for unrelated reasons (a test server we were using for download testing change behavior)
