[v5/next] documentation: "next" links points to "v4" version

[flovogt]

The UI5 CLI v5 documentation should be available under https://ui5.github.io/cli/next/.

Currently, the "next" alias points to the "v4" version.

Works

• https://ui5.github.io/cli/v4/
• https://ui5.github.io/cli/v5/
• https://ui5.github.io/cli/stable/

Works not

https://ui5.github.io/cli/next/

It seems that the GitHub Actions in v4 and main are modifying the next folder, so depending on which one ran last, it either points to v4 or v5.

This change seems to fixed the issue: a7ec66b
The problem was that Mike docs mention that versions.json is used for versions selection dorpdown.
However, the only relation between v4 and the next tag was in there!

How we verified the solution?

• Removed the next alias from versions.json
• Ran a Deploy Docs action for v4 to see whether it would overwrite the next directory and make it a synlink to v4
