fix(deps): Bump sinon to 21.0.1 in @sentry(ember)

[chargome]

• Bumps sinon from 19.0.2 to 21.0.1 in packages/ember to resolve CVE-2026-24001 (DoS via
  parsePatch/applyPatch in diff)
  • This pulls in diff@^8.0.2 (patched) instead of diff@^7.0.0 (vulnerable)
  • No breaking changes affect our usage — sinon v20/v21 only removed usingPromise,
    fakeXMLHttpRequest, fakeServer, and assert.failException, none of which we use
