8245981: Upgrade to jQuery 3.5.1

The original patch doesn't apply cleanly.

 > src/jdk.javadoc/share/classes/jdk/javadoc/internal/doclets/formats/html/HtmlDoclet.java
 > src/jdk.javadoc/share/classes/jdk/javadoc/internal/doclets/toolkit/util/DocPaths.java
 > test/langtools/jdk/javadoc/doclet/testSearch/TestSearch.java
 > test/langtools/jdk/javadoc/tool/api/basic/APITest.java
 the files have different context in 15 after [1] so I changed "jquery-3.4.1.js" to "jquery-3.5.1.js" in these files manually.

 > src/jdk.javadoc/share/classes/jdk/javadoc/internal/doclets/formats/html/resources/script-dir/external/jquery/jquery.js
 the file was removed in 15 after [2] so I replaced the file with new version for consistency

Testing: regression tests test/langtools/jdk/javadoc/ passed
