Return both failures when failed to retrive an image with a scheme

[FrimIdan]

This PR is meant to solve an issue we've got when syft failed to print the "right" error upon fetch failure.

For example, i'm trying to scan an arm64 image with an amd64 syft CLI and i'm getting the following error:

$ syft docker:idanfrim/multi-arch:only-arm64
 ⠸ Pulling image

2023/05/09 10:29:44 error during command execution: 1 error occurred:
	* failed to construct source from user input "docker:idanfrim/multi-arch:only-arm64": could not fetch image "idanfrim/multi-arch:only-arm64": unable to determine image source to select platform

The error is not clear, unable to determine image source is wrong since i've provided docker scheme.
When running the same command with debug I can see the correct failure.

$ syft -v docker:idanfrim/multi-arch:only-arm64
[0000]  INFO syft version: 0.77.0
[0003]  INFO new version of syft is available: 0.80.0 (current version is 0.77.0)
[0006]  WARN scheme "docker" specified, but it coincides with a common image name; re-examining user input "docker:idanfrim/multi-arch:only-arm64" without scheme parsing because image retrieval using scheme parsing was unsuccessful: unable to use DockerDaemon source: image has unexpected architecture "arm64", which differs from the user specified architecture "amd64"
2023/05/09 12:04:11 error during command execution: 1 error occurred:
	* failed to construct source from user input "docker:idanfrim/multi-arch:only-arm64": could not fetch image "idanfrim/multi-arch:only-arm64": unable to determine image source to select platform

So in this PR I've returned both errors so it will be more clear:

$ ./snapshot/darwin-build_darwin_amd64_v1/syft docker:idanfrim/multi-arch:only-arm64
 ⠙ Pulling image

2023/05/09 10:29:09 error during command execution: 1 error occurred:

@kzantow @tgerla Do you mind to take a look at the PR?

Hi @FrimIdan, thank you for the pull request! We've been looking at similar issues recently, and we might want to move some of this processing into stereoscope itself. We will keep this ticket updated as we investigate. Thanks again.

I believe this issue is also related: #1695

[FrimIdan]

@tgerla ok. I hope it can be sorted quickly, the current situation is confusing and my pr might be a temp solution until a better will be integrated.

@anchore/tools This is approved - waiting on a 2nd before merge!

this is a step in the right direction as it at least raises up enough information for the user to see. In a future iteration there may be opportunity to make it a little less verbose.
