feat(policy): Introduce policy engine for semantic convention registr…

…y checks

This commit introduces a new policy engine, `weaver_checker`, to validate semantic convention registries against custom rules defined using the Rego language. The engine offers enhanced flexibility and control over registry compliance checks.

Key improvements:
- Policy engine implementation: A new crate, weaver_checker, was created to wrap the `regorus` crate and provide a convenient interface for defining and executing `Rego` policies against semantic convention registries.
- Policy separation: Policy checks are now decoupled from registry loading for improved performance and maintainability.
- Policy examples: Example `Rego` policies for comparing released and unreleased versions of semantic conventions are included for reference and demonstration.
- Documentation: Comprehensive documentation on the policy engine and its usage is added, including updates to the otel-weaver-platform diagram.
- Unit tests and coverage: Unit tests were added to ensure the functionality of the policy engine, and test coverage was improved to meet project criteria.
- Registry check command: A new CLI option `--before-resolution-policies` allows applying policies before schema resolution.
