Nice 👍 I know this is still in draft, but added a couple of non blocking comments regarding error handling. Please let me know what you think

@dcelasun have you been able to test this with the binary? I'm double-checking here because I'm not seeing the error:

Before patching with your latest commit

✓ Code/test-aws-sync  $ cli sync .                                                              ⏱ 14:48:13
Loading spec(s) from .
Error: failed to get source plugin (name: cloudquery/aws@v270.23.0) information: 404 Not Found

After

💩 Code/test-aws-sync  $ cli sync .                                                             ⏱ 14:48:31
Loading spec(s) from .
Error: failed to get source plugin (name: cloudquery/aws@v270.23.0) information: 404 Not Found

Double-checking here still in case I did something wrong while testing

Fixed by the latest commit, though I'm not sure if that's the cleanest approach. One idea is to pull the version check to its own function, before isDockerPlugin and DownloadPluginFromHub but that would mean repeating network requests on the happy path.

Open to suggestions.
