Fix wally package structure

[BusyCityGuy]

Currently, the published Wally packages are missing the StateQ folder despite being included in wally.toml because the exclude * is excluding the src folder, which overrides the inclusion of subfolders of src.

This PR adds src to include, so that the src/StateQ and src/StateQ/** actually get included. This means src/TestService will still be excluded as intended because src/** is not included.
