I see issue that wants mason to manage npm here: #1286. But it's a neverending blackhole. What if npm depends on some system package that is missing? Should mason manage them as well. The easy solution I can think of it's just panic and provide a list of missing packages

Describe the solution you'd like

Check if cargo, pip, npm, etc is missing and provide a list to user when they are. Basically better error message.

Describe potential alternatives you've considered
