Classify config file and out of disk CLI errors as config errors

[angelapwen]

This PR classifies CLI errors with "out of disk" and "No space left on device" errors as configuration errors, and appends a link to https://gh.io/troubleshooting-code-scanning/out-of-disk-or-memory to the error.

It also classifies CLI errors related to invalid configuration files as configuration errors.

There are some CI failures due to a new runner image rollout: it will be fixed as of CLI v2.17.3, which will be released shortly, so this PR is probably blocked from merging until then.
