Add support for Node version 20

[poldenburg]

Renovate 38 requires node version 20.
Can you update the extension to support this node version?

[jycouet]

What is needed to support it ?

[poldenburg]

I'm not sure, maybe only update the node version, like in PR #69

@jycouet do you have time to look into this?

I just released a version 1.0.6, close the ticket if it's working :)

Great, thanks! The extension has been updated, but the pipeline still uses the old version (1.0.5), seems like a caching issue. I'll check again after the weekend.

@jycouet: Tested and working perfectly, thanks again!

A few comments:

• The task still shows version 1.0.5, because in task.json the Patch version wasn't updated to 6
• In the README NodeTool@0 is used. I suggest updating this to UseNode@1
• The task throws some warnings about deprecated packages, so maybe you could update the dependencies
