Part of #2882

Converts the Purchase pallet to the new pallet attribute macro introduced in #6877.

Following the upgrade guidelines here: https://crates.parity.io/frame_support/attr.pallet.html#upgrade-guidelines.

⚠️ Breaking Change ⚠️

From https://crates.parity.io/frame_support/attr.pallet.html#checking-upgrade-guidelines

storages now use PalletInfo for module_prefix instead of the one given to decl_storage: Thus any use of this pallet in construct_runtime! should be careful to update name in order not to break storage or to upgrade storage (moreover for instantiable pallet). If pallet is published, make sure to warn about this breaking change.

So users of the Purchase pallet must be careful about the name they used in construct_runtime!. Hence the runtime-migration label, which might not be needed depending on the configuration of the Purchase pallet.

This pallet is not used in any runtime, and thus no worries about any migration or breaking changes here. Thank you @shaunxw

Thanks Shawnx, the check-runtime CI is failing, but the current change doesn't affect any runtime in polkadot thus it is a false-negative
