chore: update runtime-go-testing workflow to Node.js 20

[Varadraj75]

Description

This pull request updates the runtime-go-testing.yml CI workflow to use Node.js 20 instead of Node.js 14, which has reached End of Life.
The change ensures the CI environment aligns with currently supported Node.js versions and avoids potential issues with modern tooling and dependencies.

This update is limited to CI configuration and does not affect the runtime behavior or public API of the library.

Closes #2424

Checklist

• The code follows the project's coding standards and is properly linted (npm run lint).
• Tests have been added or updated to cover the changes.
• Documentation has been updated to reflect the changes.
• All tests pass successfully locally.(npm run test).

Additional Notes

The CI failure observed after upgrading Node.js is due to an existing issue in the Go generator logic, which will be tracked separately. This PR intentionally focuses only on updating the CI Node.js version.

Looks like you cross polluted changes? 🤔

@jonaslagoni, thanks for catching that
You’re absolutely right — an unrelated fix commit was accidentally included.

I’ve now removed the cross-polluted changes and force-pushed the branch so this PR only updates the CI Node.js version.

Appreciate the review — please let me know if everything looks good now.

[Varadraj75]

Just to clarify for visibility:
– This PR only updates the Node.js version in runtime-go-testing.yml
– Netlify and docs-related failures are unrelated to this change
– The earlier cross-polluted commit has been removed

Happy to re-run checks or split things further if needed.
Thanks!

@jonaslagoni ,

Since this PR triggered a mix of CI, Netlify, and infra-related failures (many unrelated to the actual Node.js version bump), would it make sense to sync briefly on Slack?

I’d like to understand the expected behavior and batch any required fixes properly, instead of iterating via multiple PRs and force-pushes.

Happy to handle all necessary follow-ups to get everything fully green and aligned 👍
Thanks!
