Bump org.apache.jackrabbit:jackrabbit-webdav from 2.14.4 to 2.20.17

[slachiewicz]

Bumps jackrabbit-webdav in wagon-webdav-jackrabbit from 2.14.4 (released 2018) to 2.20.17, and removes an exclusion that the bump makes obsolete.

Why 2.20.17 and not 2.22.x

2.20.17 is the last release of the 2.20.x line, which is the newest Jackrabbit line still targeting Java 8. The switch to Java 11 landed in 2.21.23 — jackrabbit-parent goes from <java.version>1.8</java.version> (2.21.22) to <javaTargetVersion>11</javaTargetVersion> with maven.compiler.release (2.21.23), and the published jars follow:

version	max class-file major
2.20.17	52	Java 8
2.21.20 – 2.21.22	52	Java 8
2.21.23	55	Java 11
2.22.0 – 2.22.4	55	Java 11

So 2.22.x is out until Wagon raises its own baseline. 2.21.22 is technically the highest Java 8 build, but 2.21.x is Jackrabbit's unstable line, so 2.20.17 is the right target.

Dropping the commons-httpclient exclusion

2.14.4 still declared a dependency on the long-retired commons-httpclient:3.1 (the HttpClient 3 API), which this module excluded. 2.20.x drops it entirely and depends only on httpclient 4.5.14 / httpcore 4.4.16, so the exclusion is now dead configuration. The commons-logging exclusion is kept — that one still comes in via httpclient 4.5.14.

The resulting dependency tree gains no new artifacts beyond commons-codec:1.11 under httpclient.

Verification

• Full reactor builds clean.
• wagon-webdav-jackrabbit tests: 283 run, 0 failures, 0 errors, 0 skipped.
• Enforcer's enforce-bytecode-version rule passes, confirming 2.20.17 satisfies the Java 8 baseline.

Note: mvn verify currently fails the drop-legacy-dependencies enforcer rule on plexus-container-default:2.1.1 coming from wagon-provider-test. I confirmed that failure is pre-existing on an unmodified master and unrelated to this change.

CI is green on all 8 cells, including the three JDK 8 ones — which directly confirms 2.20.17 is fine for the Java 8 baseline.

The drop-legacy-dependencies enforcer failure I mentioned above did not occur in CI; it only reproduces locally where enforcer resolves to 3.6.3. Please disregard that note.
