Errors from build.rs aren't shown in editor

[Cobrand]

Version of VSCode: 1.72.2 Version of the extension: 0.4.2 OS: x86_64 Linux

Description: If the build.rs file (or equivalent) has a compilation error in it, no errors are shown in the editor. This of course also prevents regular errors from the src/ folder to be hidden until build.rs can be compiled again.

• It looks like RLS sends the right output to vscode, but it just seems that the extension can't pick up the errors properly.
