Fix reflection invocation of PdeLanguageServer

[ovalnine]

Fixed argument type mismatch when invoking the PdeLanguageServer main method via reflection.

Changed from using spread operator with a list wrapper to passing a properly typed String array directly.

This resolves the IllegalArgumentException thrown during language server initialization.

Thank you @ovalnine I had noticed this myself as well in another branch I was working on.
