This proposal aims to schedule the set of parachain auctions on Polkadot in 2023 (LP12-LP15) to ensure that all auctions are properly scheduled throughout the year and the community can continue including new parachains and allowing those already up and running to renew their slots in 2023.

This proposal suggests two actions in LP12 and LP13 each, followed by seven auctions per LP14 and LP15, in a total of 18 auctions until the end of the year. Full details of the schedule can be found in the calendar [here](https://docs.google.com/spreadsheets/d/1audL4P9LhCIFuX9AXB5K7cQEvn4JgukBmcA_vxwYfTY/edit#gid=218733256).


Schedule a majority-carries referendum to be tabled next once it is legal to schedule
an external referendum.

The dispatch of this call must be `ExternalMajorityOrigin`.

- `proposal_hash`: The preimage hash of the proposal.

Unlike `external_propose`, blacklisting has no effect on this and it may replace a
pre-scheduled `external_propose` call.

Weight: `O(1)`

Send a batch of dispatch calls.
Unlike `batch`, it allows errors and won't interrupt.

May be called from any origin except `None`.

- `calls`: The calls to be dispatched from the same origin. The number of call must not
  exceed the constant: `batched_calls_limit` (available in constant metadata).

If origin is root then the calls are dispatch without checking origin filter. (This
includes bypassing `frame_system::Config::BaseCallFilter`).
