ci(workflows): refactor integration tests

[pinglin]

Because

• we can safely run the integration tests on only Linux because instill-core relies on Docker Desktop on MacOS.
• as the codebase continues to evolve the timeout 60 for the integration tests is no longer enough

This commit

• remove integration tests for MacOS
• increase timeout to 120
• upgrade to actions/checkout@v4 to address the warning:
• disable image build in integration-test

The following actions use a deprecated Node.js version and will be forced to run on node20: actions/checkout@v3. For more info: https://github.blog/changelog/2024-03-07-github-actions-all-actions-will-run-on-node20-instead-of-node16-by-default/
