Tries to read non-existing file Marlin\src\inc\Conditionals-1-axes.h

Nobody has claimed this yet.

The extension crashes with the following stack trace. I have no idea why it would try to open a file called `Marlin\src\inc\Conditionals-1-axes`, since nothing in Marlin references a file of that (or similar) name.

This is on VsCode 1.94.2

```

Start with abm/editor.js, especially combinedSchema at line 123 and its caller around line 150, then inspect extension.js at line 14. Reproduce the crash with VS Code 1.94.2 and the reported Marlin project, determine why the missing Conditionals-1-axes.h path is requested, and verify that the extension no longer crashes when this file is absent.
