styling improvements for holesky.md (#5420)

- compact syntax for different options (as in the rest of the guide)
- correct numeration of the list (continuation vs starting from 1)
- add links to useful resources
- a note stating that Prater is deprecated

     ## Obtaining genesis file (optional)
 
-By default, Nimbus will automatically download the genesis state of Holešky from Github through the HTTPS protocol. If something prevents you from using this method, you may be able to work-around the issue by either instructing Nimbus to use a different URL by specifying the `--genesis-state-url` command-line parameter (for example, you can point it to the `/eth/v2/debug/beacon/states/genesis` endpoint of a trusted beacon node or a checkpoint provider) or by downloading the `genesis.ssz` file of the network through some other means and then supplying its path through the `--genesis-state` command-line parameter.

 # Prater testnet
 
+!!! note
+    Prater/Goerli is deprecated as of January 2023.
+    It will be supported long term for another 12 months.
+    Please consider using [Holesky testnet](./holesky.md) moving forward.
+
+
 `prater`, also known as `goerli`, is the current long-running merge testnet.
 It provides an opportunity to verify your setup works as expected through the proof-of-stake transition and in a post-merge context as well as to safely practice node operations such as adding and removing validators, migrating between clients, and performing upgrades and backups.
 If you come across any issues, please [report them here](https://github.com/status-im/nimbus-eth2/issues).
