deprecated_stop() should say defunct instead of deprecated

> lifecycle::deprecate_stop("1.0.0", "foo()", "foo(bar = )")
Error: `foo()` is deprecated as of <NA> 1.0.0.
Please use the `bar` argument instead.

This isn't a straightforward change because it requires providing a full deprecation cycle as package versions. Or at least change the meaning of the version in deprecate_stop() so that it represents the version at which the function stopped working instead of the version at which it was deprecated.

The UI was made to minimise intervention when bumping the lifecycle, so that all _warn can be bumped to _stop by bulk search&replace for instance.

Maybe “foo() was deprecated in PKG VERSION and is now defunct”?

why didn't I think of that :)
