javadoc has supported HTML 5 since JDK 9 (JDK-8072945) and warned about use of HTML 4 since JDK 11 (JDK-8182765)

It is time to remove support for HTML 4.

The -html4 option and the code to generate HTML will be removed, so that the doclet always generates HTML 5.  The -html5 will remain, but will effectively be ignored.
The work primarily consists of removing all references to the enum `HtmlVersion` and the field `HtmlConfiguration.htmlVersion`, and resolving any `if` statements in favor of HTML 5.

There may be additional references to HTML 4 in doclint. See the javac --doclint-format option. $ ./build/linux-x86_64-server-release/images/jdk/bin/javac -X --doclint-format {html4,html5} Specify the format for documentation comments
