Remove unnecessary job dependencies in CI workflow

Remove 'needs: [build]' dependencies for unit tests, linting, license
check, and ko-resolve jobs. These jobs don't actually need to wait for
the build job - they each build independently as part of their setup.

This allows unit tests and other fast checks to run in parallel
immediately when a PR is created, rather than waiting for the build
job to complete first.
