fix(telemetry): fix CI linker errors, check-rename, and docs build

- Add ValidationTracker.cpp to xrpl.test.telemetry target sources
  (implementation lives in src/xrpld/ but has no OTel SDK dependency)
- Change BEAST_DEFINE_TESTSUITE namespace from ripple to xrpl
- Replace recursive *.md glob with non-recursive GLOB in XrplDocs.cmake
  to avoid picking up .claude/instructions.md
