chore: Upgrades NodeJS to 20

[tuliomir]

Acceptance Criteria

• Upgrades Node.JS from 14 to 20
• Adjusts the GitHub Workflow branches to the new Release process, an oversight from chore: New release process #632

Security Checklist

• Make sure you do not include new dependencies in the project unless strictly necessary and do not include dev-dependencies as production ones. More dependencies increase the possibility of one of them being hijacked and affecting us.
