[feature] Full support for Node.js 20

[Water-Melon]

Hi team,

I hope you're doing well. I wanted to inquire if there are any plans for a new release. We've recently bumped the actions to avoid the dependency on Node.js 16, but some actions in version 2.0.0 still rely on it.

Looking forward to hearing from you!

Hey, Yes we're planning to also upgrade the actions to use node20. We would also welcome a PR.

I noticed that the action on the main branch, as well as the other actions it uses, are already based on Node 20, so only the next version release is needed. Since Node 16 will reach end of life in the Actions runner, I think releasing the next version is quite necessary.

Although the actions in v2.0.0 of slsa-github-generator are already based on Node 20, some of the other actions they use still depend on Node 16. For example: https://github.com/slsa-framework/slsa-github-generator/blob/v2.0.0/.github/workflows/builder_container-based_slsa3.yml#L309.

@ramonpetgrave64 Is there any ETA on the release with the support for Node20?

Currently it takes about a week to do a proper release procedure. For now, I'll estimate to begin in the week of Feb 3.
