Bug: DockerDistributionAPIError suppresses error information

[Patman12]

Description:

When sam local invoke --debug fails due to an unknown Docker APIError, the only output you see is Error: Unknown API error received from docker. Since this error handling was added in v1.83.0, I reverted to v1.82.0 to investigate and noticed the error was instead Error: 500 Server Error: Internal Server Error ("Get "https://public.ecr.aws/v2/": net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers)").

Steps to reproduce:

Not sure how to consistently reproduce the issue, but any non-404 APIError from docker will cause sam local invoke to fail with this error

Observed result:

Only output relevant to the failure is Error: Unknown API error received from docker even with --debug set.

Expected result:

The original APIError returned from Docker should be shown in the output

1. OS: macOS Monterey
2. sam --version: 1.86.1
3. AWS region: N/A
