[ NEW PAGES ] More content for cliffordising circuits

[javabster]

Currently our Verify section only covers information for using simulators, but there are more things that quantum software users can be doing as "verification" steps other than simulation.

For example, this section could include more details on cliffordising circuits (maybe based on some content from practitioners forum?)

@haimeng-zhang gave a presentation at a practioner's forum that contains useful material. She can provide her slides. This can be adapted into a page that explains how to Cliffordize circuits for estimating resources for error mitigation.

Material would fit well in Debugging tools (since Verify section no longer exists) cc: @kaelynj
