Sometimes you need to debug some issues just by the logs and reconstruct
what happened.
In these scenarios it would be nice to know if a block was imported as
best block, and what it parent was.
So here I propose to change the output of the informant to this:

```
2024-04-05 20:38:22.004  INFO ⋮substrate: [Parachain] ✨ Imported #18 (0xe7b3…4555 -> 0xbd6f…ced7)    
2024-04-05 20:38:24.005  INFO ⋮substrate: [Parachain] ✨ Imported #19 (0xbd6f…ced7 -> 0x4dd0…d81f)

```
