Indian GST return reporting now uses the existing EDI production environment setting instead of a separate GST-specific setting. This reduces configuration duplication and helps ensure GST reports follow the same production/test mode as other Indian e-invoicing features.

Before this PR:-
l10n_in_gstr_gst_production_env not needed because we already have

After this PR:-
Change the value coming from l10n_in_gstr_gst_production_env to
l10n_in_edi_production_env.
