[Feature] Add the paths filters to conformance CI tests

Problem Statement

Ideally conformance tests should be triggered on code changes only. To speed up CI jobs for non-code changes, we can add the paths filter to conformance, target paths to include:

• pkg/**
• api/**
• cmd/**
• charts/**
• ext/**
