no-issue: disable tests conditionally when binary is not present

[ricardozanini]

Many thanks for submitting your Pull Request ❤️!

What this PR does / why we need it:
Sometimes, a local machine environment might not have python or protoc installed to run "unit" tests. In my opinion, these tests should be ITs and be on a specific profile.

However, if we want to run as unit tests and they depend on the environment where they're running, we disable the test if needed.

Special notes for reviewers:
mvn clean install now runs smoothly if python or grpc are not available.

Pull request overview

Adds a JUnit 5 annotation/extension to conditionally disable tests when required external binaries (e.g., protoc, python) are not available on the executing machine, improving mvn clean install reliability across environments.

Changes:

• Introduce @DisabledIfBinaryUnavailable plus BinaryCheckCondition JUnit 5 ExecutionCondition.
• Apply the new annotation to gRPC tests requiring protoc.
• Apply the new annotation to the parameterized custom function test requiring python.
