Add NOTES.txt to the apache-tika chart

Tika has no Ingress, so the notes lead with the cluster-internal URL, the
Service-port-80 to container-port-9998 mismatch a consumer has to get right,
and /parsers as the direct answer to "why did this file come back empty".

Two warnings come from measuring the running container rather than from
reading the values file:

- The image tag has to keep its "-full" suffix. That variant is where
  Tesseract 5.5.0 and the extra parsers live; the plain image carries no
  tesseract binary at all, so dropping the suffix does not fail loudly, it
  just stops OCR and returns empty text for scans.
- The JVM never sees the container limit. It starts without -Xmx and derives
  its heap from the limit at MaxRAMPercentage=25, so the number worth sizing
  against is a quarter of it.

The heap figure is computed from the effective limit through the chart's own
null-safe effectiveResources helper, so an erased resources: block still
prints the defaults the container actually receives instead of dropping the
paragraph. Refs #43.
