Modularize Almanac Network transactions

Summary: Depends on D19321. Ref T13120. Ref T12414. Move transactions for Almanac Networks (just "name") to ModularTransactions.

Test Plan:
  - Created a new network.
  - Renamed a network.
  - Tried to create a network with no name (got an error).
  - Grepped for `AlmanacNetworkTransaction::`.
