fix(gatsby): remove resource query from warnings

[marvinjude]

Description

warn ./src/pages/index.js?export=default
Attempted import error: 'red' is not exported from './index.module.scss' (imported as 'styles').
warn ./src/pages/index.js?export=head
Attempted import error: 'red' is not exported from './index.module.scss' (imported as 'styles').

With the introduction of Head API, the modulePath can have a resourceQuery so this removes ?export=head from the error above
