Misleading CLI error regarding `track.yml`

[nol166]

Issue

On a few occasions, I and some members of my team have encountered an issue when attempting to push to instruqt. The CLI reports an error with the track.yml file, but the actual error seems to be with the assignment.md file in the teaser or contents properties.

Track info

slug: multi-analyzer
org: mongodb-dev

Error

Actual issue:

In assignment.md, the issue actually seems to an improperly formatted teaser or contents property in the front-matter. If the indenting is off, it exits with an error

Suggested change

It seems like a more accurate error message in the CLI could mitigate some issues for users. There have been instances in the slack channel of this very issue impacting other teams as well. An error message that is specific to the file that is causing the problem would be better.
