What does this implement/fix? Explain your changes.

Currently when the wp-graphql-woocommerce plugin is activated I'm getting CORS errors during clientside queries. I've tracked the the problem down and I found out that the plugin is still using a deprecated function that causes it.

Since Woocommerce v5.3.0 the nonce_user_logged_out function used in the session handler is deprecated. This PR replaces that function with the new maybe_update_nonce_user_logged_out.

Does this close any currently open issues?

Not that I know of.
