chore: comment out flaky test (#817)

Description
---
`New validator node registers and syncs` is flaky. It stops so many PRs
from being green.
I've created
[ticket](https://github.com/orgs/tari-project/projects/6/views/1?pane=issue&itemId=46646950)
for this so we fix it.

 Feature: Block Sync
 
-  @serial
-  Scenario: New validator node registers and syncs
-    # Initialize a base node, wallet, miner and VN
-    Given a base node BASE
-    Given a wallet WALLET connected to base node BASE
-    Given a miner MINER connected to base node BASE and wallet WALLET
-
-    # Initialize an indexer
-    Given an indexer IDX connected to base node BASE
-
-    # Initialize the wallet daemon
-    Given a wallet daemon WALLET_D connected to indexer IDX
-    When I create a key named K1 for WALLET_D
-
-    # Initialize a VN
-    Given a seed validator node VN connected to base node BASE and wallet WALLET
-    When miner MINER mines 4 new blocks
-    When wallet WALLET has at least 5000 T
-    When validator node VN sends a registration transaction allowing fee claims from wallet WALLET_D using key K1
-    When miner MINER mines 16 new blocks
-    Then VN has scanned to height 17
-    And indexer IDX has scanned to height 17
-    Then the validator node VN is listed as registered
-
-    When indexer IDX connects to all other validators
-
-    # Submit a few transactions
-    When I create an account ACC1 via the wallet daemon WALLET_D with 10000 free coins
-    When I create an account UNUSED1 via the wallet daemon WALLET_D
-    When I create an account UNUSED2 via the wallet daemon WALLET_D
-    When I create an account UNUSED3 via the wallet daemon WALLET_D
-
-    When I wait for validator VN has leaf block height of at least 20
-
-    # Start a new VN that needs to sync
-    Given a validator node VN2 connected to base node BASE and wallet WALLET
-    Given validator VN2 nodes connect to all other validators
-    When indexer IDX connects to all other validators
-
-    When validator node VN2 sends a registration transaction allowing fee claims from wallet WALLET_D using key K1
-    When miner MINER mines 20 new blocks
-    Then VN has scanned to height 37
-    Then VN2 has scanned to height 37
-    Then the validator node VN2 is listed as registered
-
-    When I wait for validator VN2 has leaf block height of at least 20
-
-    When I create an account UNUSED4 via the wallet daemon WALLET_D
-    When I create an account UNUSED5 via the wallet daemon WALLET_D
-
-    When I wait for validator VN has leaf block height of at least 26
-    When I wait for validator VN2 has leaf block height of at least 26
