feat: add support for runtimeConfigModule w/ Trans

[arcanis]

The runtimeConfigModule setting cannot be used to transform the hardcoded import {Trans} from '@lingui/react' statements, which is problematic when the Trans symbol is expected to be provided by an intermediary layer (#822).

This diff addresses that by adding support for runtimeConfigModule being an object, in which case the key is the symbol name (either i18n or Trans), and the value is the symbol name and from where to import it. This change is completely backward compatible, only adding syntax.

The test framework doesn't seem to allow for testing runtimeConfigModule (its current implementation doesn't seem tested) so I couldn't add relevant tests.
