MarkLee131 c336a1595d Java: split read-only path sinks into path-injection[read] 
Introduce a new Models-as-Data sink sub-kind path-injection[read] for
models that only read from or inspect a path. The general
java/path-injection query and its PathInjectionSanitizer barrier
continue to consider both path-injection and path-injection[read]
sinks, so no alerts are lost. The java/zipslip query deliberately
selects only path-injection sinks, since read-only accesses such as
ClassLoader.getResource or FileInputStream are outside the archive
extraction threat model.

Addresses https://github.com/github/codeql/issues/21606 along the lines
proposed on the issue thread: prefer path-injection[read] over a
[create] sub-kind so that miscategorizing a sink causes a false
positive (easy to spot) rather than a false negative.

- shared/mad/codeql/mad/ModelValidation.qll: allow path-injection[...]
  as a valid sink kind.
- java/ql/lib/ext/*.model.yml: relabel the models that PR #12916
  migrated from the historical read-file kind (plus the newer
  ClassLoader resource-lookup variants that share the same read-only
  semantics).
- java/ql/lib/semmle/code/java/security/TaintedPathQuery.qll and
  PathSanitizer.qll: select both path-injection and
  path-injection[read] sinks/barriers.
- java/ql/lib/semmle/code/java/security/ZipSlipQuery.qll: keep only
  path-injection, with a comment explaining why path-injection[read]
  is excluded.
- java/ql/test/query-tests/security/CWE-022/semmle/tests/ZipTest.java:
  add m7 regression covering the Dubbo-style classpath lookup from
  issue #21606 and assert no alert is produced.
- Update TaintedPath.expected for the renamed kinds in the models list.
- Add change-notes under java/ql/lib/change-notes and
  java/ql/src/change-notes.
