Exclude Wayback Machine URLs from link checks

The structure101 fix (commit f9eb8a2) points at a Wayback snapshot.
That URL works in browsers and from Linux/macOS CI, but Azure-hosted
Windows runners hit java.net.SocketTimeoutException on connect,
failing the integration test's gradle-plugin job (and presumably
the maven-plugin and self-check paths too) when the matrix includes
windows-latest.

Add 'https://web.archive.org/.*' to the excludes lists in all three
HSC invocations that check ../common/build/docs/README.html. This
keeps the historical reference visible to readers while avoiding the
Windows-only network flake.
