Fully deprecate accessible-emoji rule

[backwardok]

The accessible-emoji rule got marked as deprecated to address #627, but was never removed from the rule set.

This removes the rule from the strict and recommended lists and also updates the readme to reflect it being deprecated.

@ljharb is there a way to retry a test or do I have to rebase and push again to trigger the tests to rerun?

[ljharb]

@backwardok i think only a maintainer can retry one; otherwise the typical way is to close and reopen the PR. In this case, the task is failing because when rebased, there's merge conflicts. Feel free to ignore this tho; we can rebase it for you when it's ready to land.

Thanks @ljharb !
