docs: fix source file extension for vala in 01-sources-files.rst (#79)

Tbusk · web-flow · commit f2f10be9196d · 2025-06-08T13:18:02.000+01:00
Currently, the source file in developer guide for c# developers suggests
 that `.cs` is the source file extension for vala source files rather
 than `.vala`.  This changes it to `.vala`.
