Consider using gtksourceview module from the runtime

GNOME runtime already provides the **gtksourceview** module.

In most cases, you don't need to build this module separately, unless your project requires a specific version or a custom configuration.

If you have a specific reason to build the module, please add notes to the manifest file.

Thanks.

**GNOME 49**
