fix(copilot-review): suppress Article schema on versioned docs roots too

Addresses Copilot comment 3081151415 on PR #832.

The previous suppressArticleSchema check only matched /docs/ as the
docs root, but this site serves versioned hub pages too — /docs/4.0.0/,
/docs/3.0.0/, /docs/2.0.0/, /docs/1.0.0/ — via onlyIncludeVersions and
includeCurrentVersion in docusaurus.config.js. Each versioned root is
also an index of content with no single author/date/headline, so
emitting Article/BlogPosting/APIReference schema on those pages had
the same type-mismatch problem the base case fix was addressing.

Added a regex check for /docs/<digit-starting-version>/ so any current
or archived versioned root is caught by the same suppression path.
Current content pages inside versioned trees (e.g.
/docs/4.0.0/keploy-explained/how-keploy-works/) still emit Article
schema as normal since they have real authors, dates, and headlines —
only the bare versioned roots are suppressed.
