chore: update to latest changes in tangle

[shekohex]

This pull request includes several updates across multiple files, focusing on dependency updates, code refactoring, and metadata extraction improvements. The most important changes include upgrading dependencies, refactoring hooks and job extraction logic, and introducing new metadata extraction functions.

Mainly, the new changes we are introducing in the tangle-network/tangle#794 removes the notion of separate hooks and instead unifies everything in one filed called manager in the Service Blueprint. This field will be set to the EVM Smart contract that manages the lifecycle of a the blueprint instances.

# Cargo.toml

[package.metadata.blueprint]
manager = { evm = "IncredibleSquaringBlueprint" }

No more #[job(verifier(evm = "IncredibleSquaringBlueprint"))] on top of each job. This manager has a onJobResult and onJobCall hooks where you can do your normal validation and verification if you want. (by default they are no_op)

Dependency Updates:

• Cargo.toml: Updated tangle-subxt dependency from version 0.3.0 to 0.4.0.
• blueprint-metadata/Cargo.toml: Added serde as a workspace dependency.

Code Refactoring:

• blueprint-metadata/src/lib.rs: Refactored imports to include cargo_metadata and rearranged existing ones.
• blueprint-metadata/src/lib.rs: Replaced generate_gadget function with extract_metadata and extract_blueprint_manager functions for better modularity.
• blueprint-metadata/src/lib.rs: Removed ServiceRegistrationHook and ServiceRequestHook from the Hook enum and related logic. [1] [2]

Metadata Extraction:

• blueprint-metadata/src/lib.rs: Introduced extract_metadata and extract_blueprint_manager functions to handle metadata extraction from the package.
• blueprints/incredible-squaring/Cargo.toml: Added blueprint manager metadata.

Submodule Updates:

• blueprints/incredible-squaring/contracts/lib/forge-std: Updated submodule commit reference.
• blueprints/incredible-squaring/contracts/lib/tnt-core: Updated submodule commit reference.
