Improve scip snapshot default documentation output

[varungandhi-src]

We should improve the default scip snapshot output to not have truncated documentation lines. Right now, it seems to generate output with a single line of documentation by default, which just ends up being:

 //  documentation ```ts

for TypeScript. This isn't useful. Instead, perhaps we should default to omitting that line if the doc comment is empty/blank, and print the full doc comment if one is present.
