Docs: Description of LOAD_CLOSURE in dis module should be updated

[c2170]

Documentation

In the description of LOAD_CLOSURE, I think there is no longer exists co_fastlocalnames attribute. It may need to be updated.

Looks like this was added in PR #26388, but I also see a revert and unrevert in its issue, #87859...

Let's ask @ericsnowcurrently: should this reference to co_fastlocalnames be removed from the docs?

I think this was corrected in PR #106059 @hugovk @c2170
