fix(clustered): correct anchor link in scale-cluster documentation

Fix broken internal anchor link from #rrecommended-scaling-strategies-per-component
to #recommended-scaling-strategies-per-component (removed extra 'r').

This was used to test the improved link-checker anchor validation functionality.

+### Link Resolution Behavior
+
+The link-checker automatically handles relative link resolution based on the input type:
+
+**Local Files → Local Resolution**
+```bash
+# When checking local files, relative links resolve to the local filesystem
+link-checker check public/influxdb3/core/admin/scale-cluster/index.html
+# Relative link /influxdb3/clustered/tags/kubernetes/ becomes:
+# → /path/to/public/influxdb3/clustered/tags/kubernetes/index.html
+```
+
+**URLs → Production Resolution**
+```bash
+# When checking URLs, relative links resolve to the production site
+link-checker check https://docs.influxdata.com/influxdb3/core/admin/scale-cluster/
+# Relative link /influxdb3/clustered/tags/kubernetes/ becomes:
+# → https://docs.influxdata.com/influxdb3/clustered/tags/kubernetes/
+```
+
+**Why This Matters**
+- **Testing new content**: Tag pages generated locally will be found when testing local files
+- **Production validation**: Production URLs validate against the live site
+- **No false positives**: New content won't appear broken when testing locally before deployment
