[Feature]: Remove Distinction between Warnings and Errors

[garrettmflynn]

What would you like to see added to the NWB GUIDE?

Based on our team discussion of the Dev Hackathon results, we determined it would be useful to remove the distinction between warnings and errors on the GUIDE. This will help reduce the user's cognitive load and increase their adherence to Best Practices.

Do you have any interest in helping implement the feature?
