In an attempt to make our documentation HTML5 compliant, we want to clean up all the warnings reported by tidy against our documentation.

if you look at
 https://docs.oracle.com/en/java/javase/22/docs/specs/man/jfr.html and look for "jfr configure subcommand", you will see
"The syntax is:

jfr configure [--interactive] [--verbose] [--input ] [--output ] [option=value]* [event-setting=value]*"

when it actually is " `jfr configure` \[--interactive\] \[--verbose\]
               \[--input <files>\] [--output <file>\]
               \[option=value\]* \[event-setting=value\]*"

This is because the `<` is not correctly escaped in "<files>" for example and should be "&lt;file>"

The tidy tool reported a few more problems in the jfr.html man page
