fix(docs): drop the archived VS Code extension content source

The playbook pulled docs from reqstool-vscode-extension, which is archived and
private -- so Antora cannot fetch it and the Pages build has failed since
2026-05-27:

  FATAL (antora): Content repository not found or requires credentials
  (url: https://github.com/reqstool/reqstool-vscode-extension)

That repo is superseded by reqstool-vscode and is no longer used, so the source
is removed rather than repointed: reqstool-vscode carries no docs module to
point at.

The three pages that cross-referenced the removed module would have rendered as
broken links, so they now link to the repository directly. When reqstool-vscode
grows a docs module, these can go back to being xrefs and the source can be
added again.
