Description

This updates the docs for wp.data.subscribe for changes in #5003

How Has This Been Tested?

• Pulled master, and ran the build script.
• Put code in a block.
• Saw it logged correctly.

• [x ] My code is tested.
• [x ] My code follows the WordPress code style.
• [x ] My code has proper inline documentation.

The Documentation of the data module is meant to be generic. Should we document these selectors as part of the editor module's documentation instead?

Also, in Calypso we have a script to generate selectors documentation automatically, we might be able to adapt it here cc @aduth

The API for select has been revised as of #5007.

Also, you may be encountering errors because tests were briefly failing on master which was resolved in 6619a9f. You can remedy this by rebasing and pushing your branch:

# Assuming "upstream" is WordPress/Gutenberg
git checkout patch-2
git rebase upstream/master
git push -f origin patch-2

[aduth]

Any chance you'd be able to update this for the changes introduced by #5007?

Per Riad's feedback, I feel as though this should be limited to updating from:

getEditedPostSlug

To:

getEditedPostAttribute( 'slug' )
