Fix resource loading in HtmlSanitizerFuzzerTest

[jospint]

Summary

Fix the failing HtmlSanitizerFuzzerTest.testFuzzHtmlParser test that was causing CI builds to fail.

Problem

The test was using org.apache.commons.codec.Resources.getInputStream() to load the benchmark resource file benchmark-data/Yahoo!.html. This method uses the thread's context class loader, which may not have the test resources on its classpath in certain execution environments like GitHub Actions with Maven Surefire.

java.lang.IllegalArgumentException: Unable to resolve required resource: benchmark-data/Yahoo!.html
    at org.apache.commons.codec.Resources.getInputStream(Resources.java:41)
    at org.owasp.html.HtmlSanitizerFuzzerTest.testFuzzHtmlParser(HtmlSanitizerFuzzerTest.java:66)

Solution

Replace the commons-codec Resources utility with the standard Java class loader approach:

getClass().getClassLoader().getResourceAsStream("benchmark-data/Yahoo!.html")

This is more reliable because it uses the same class loader that loaded the test class itself, guaranteeing the resource will be found since both the test class and the resource file are in the same classpath scope (target/test-classes/).

Changes

• Removed org.apache.commons.codec.Resources import
• Added java.io.InputStream import
• Used standard Java resource loading with try-with-resources to properly handle the stream

Testing

• All 324 tests pass locally with ./mvnw -B verify

Yep this was the same fix I made in my PR to get it to pass. I will rebase with this change.
