label-content-name-mismatch is experimental it's still displayed

[adamraine]

Transfer from GoogleChrome/web.dev#10417 which makes a good point that we shouldn't display experimental audits in a11y. A good solution would be to hide this audit until it's non-experimental.

Do we have any additional motivation to display this audit?

@adamraine, @jazyan, @brendankenny, @rviscomi what timeline should I communicate to my stakeholders for fixing this issue?

These are all the audits we enabled but are marked experimental:

label-content-name-mismatch
table-fake-caption
td-has-header

#15051 #15098 #15298

Why is it marked experimental? Couldn't figure that out. https://github.com/dequelabs/axe-core/pull/4063/files#diff-4d68b3cb376284c272c2dd07c785636054d37d9dd714e7160b280032ffcdbd03L4

Thanks all! 🙇

I've dropped a question with the Axe team to see when label-content-name-mismatch might come out of experimental.

Could Lighthouse users have an option to run Experimental rules if they wanted in the meantime?
