Improve quickstart

[nalepae]

Main changes:

• Geth:
  • Remove the usage of the Geth installer as it seems not to be maintained any more. (Or at least I did not find it on Geth download page.)
  • Explicitly set the IPC file location, as the default location created by Geth does not match what the documentation currently use in the Prysm BN command line for MacOS.
• Nethermind:
  • Explicitly set the IPC file location
  • Add win/others cases
• Replace usage of Goerli-Prater by Goerli since even the EF https://prater.launchpad.ethereum.org/en/ redirects to https://goerli.launchpad.ethereum.org/en/ without any mention of the word prater. (However, added a note to explained why the genesis.ssz file is still located under the prater directory.
• Add usage of --suggested-fee-recipient option in the Prysm VC command line.
• Reduce some "code" duplications by adding some Win/others or mainnet/testnets if/else cases where needed
• Fix some broken links
• Add some missing holesky/sepolia commands
• Add --mainnet flag everywhere on mainnet to be more explicit
• Add a link to the checkpoint sync page
