[ETCM-8382] feat: use paritytech polkadot-sdk

[LGLO]

Description

Switches dependencies to Paritech polkadot-sdk.

We lose our fn starting_timestamp but there is a ticket to use fn timestamp that will be in the next polkadot stable release: https://input-output.atlassian.net/browse/ETCM-8382 with instructions where to use it.

Our major sync fork fix is not in polkadot-stable2407 as well, but seems that MC follower caching helped a lot here because the sync speed I've observed is 230-305 blocs per second, so it is approx x1500 speed - should be totally fine and with major sync fix it can get better.
