false positive warning about library files not being well-supported

This happens for all standard library modules, and also for well-configured dependencies in other libraries.

I have also seen this and had no idea what it meant, whether this was harmful or what to do about it.

Question 1: who generates this and why?

[jurgenvinju]

If you open a file outside of the srcs folders in the pathconfig then editor features like the static checker don't work well. The rascal lsp server checks this and produces the error.

I think it doesn't consider files in library folders that have .tpl files. Because these are also well supported by the LSP server.

We got to improve this heuristic to not fire for library files that are openend, as we have special support for them.

Also, we discussed that missing pom.xml files see #443 and #434 should be fined tuned a bit more.
