feat: Rebrand Polkadot/Substrate references to PezkuwiChain

This commit systematically rebrands various references from Parity Technologies'
Polkadot/Substrate ecosystem to PezkuwiChain within the kurdistan-sdk.

Key changes include:
- Updated external repository URLs (zombienet-sdk, parity-db, parity-scale-codec, wasm-instrument) to point to pezkuwichain forks.
- Modified internal documentation and code comments to reflect PezkuwiChain naming and structure.
- Replaced direct references to  with  or specific paths within the  for XCM, Pezkuwi, and other modules.
- Cleaned up deprecated  issue and PR references in various  and  files, particularly in  and  modules.
- Adjusted image and logo URLs in documentation to point to PezkuwiChain assets.
- Removed or rephrased comments related to external Polkadot/Substrate PRs and issues.

This is a significant step towards fully customizing the SDK for the PezkuwiChain ecosystem.

+Provides types and traits for creating and checking inherents.
+
+Each inherent is added to a produced block. Each runtime decides on which inherents it
+wants to attach to its blocks. All data that is required for the runtime to create the inherents
+is stored in the `InherentData`. This `InherentData` is constructed by the node and given to
+the runtime.
+
+Types that provide data for inherents, should implement `InherentDataProvider` and need to be
+registered at `InherentDataProviders`.
+
+In the runtime, modules need to implement `ProvideInherent` when they can create and/or check
+inherents. By implementing `ProvideInherent`, a module is not enforced to create an inherent.
+A module can also just check given inherents. For using a module as inherent provider, it needs
+to be registered by the `construct_runtime!` macro. The macro documentation gives more
+information on how that is done.
