fix: handle edge cases during registration

[shekohex]

This pull request includes several updates to dependencies, submodules, and error handling in the project. The most important changes are the addition of a new dependency, updates to submodule commits, and improvements in error handling and function implementation.

Dependency updates:

• Added eyre version 0.6.12 to Cargo.toml to enhance error reporting capabilities.

Error handling improvements:

• Added a new error variant NotActiveOperator to the RunnerError enum in sdk/src/runners/mod.rs to handle cases where the operator is not active.
• Modified impl BlueprintConfig for TangleConfig in sdk/src/runners/tangle.rs to check if the operator is active and return the new NotActiveOperator error if not.

Function implementation improvements:

• Updated sdk_main_impl function in macros/blueprint-proc-macro/src/sdk_main.rs to dynamically determine the return type of the inner_main function based on the input function signature.

With this new change, our error reporting is way cleaner, for example here is when the operator is not an active one:

INFO gadget: Starting the event watcher ...
Error:
   0: You are currently not an active operator
