fix: 🔧 align BabeDataGetter implementation for all runtimes (#152)

Browse source 
Based on [this
comment](https://github.com/datahaven-xyz/datahaven/pull/148#pullrequestreview-3195433668),
I took the SH
[implementation](3e5f774c64/runtime/solochain-evm/src/configs/mod.rs (L1124))
of the `BabeDataGetter` and aligned all three runtimes with this
implementation.
