[v25] Anchors without `--` prefix

[regseb]

Affected URL(s)

https://nodejs.org/docs/latest-v25.x/api/cli.html#permission

Description of the problem

• In v24, HTML anchors have the prefix --. For example, for the heading --permission, the anchor is also --permission.
• In v25, the prefix is removed. For the heading --permission, the anchor is permission.

The links haven't been changed, so they still go to the correct page, but they don't scroll to the right spot.

• File System - manageable through --allow-fs-read, --allow-fs-write flags

---

Either the problem comes from how the anchors are generated, or all the links need to be corrected.

Looks like we explicitly remove these https://github.com/nodejs/doc-kit/blob/main/src/generators/metadata/constants.mjs#L10-L11
