Is there some documentation explaining how to craft the xcm call from a parachain to the relay chain's registrar.swap extrinsic (in the context of extending the parachain lease period)?

Hey you can find the answers in the Polkadot wiki and reference another parachain's team's governance proposal and XCM call parameters for guidance:
- Polkadot wiki: https://wiki.polkadot.network/docs/learn-auction#lease-extension-with-overlapping-slots
- Moonbeam's example: https://polkadot.polkassembly.io/referenda/139
- The equivalent call on SubScan: https://polkadot.subscan.io/referenda_v2/139
