Security Center recommendations and their corresponding policy names are aligned

To illustrate the connection between recommendations and their matching security policies, we have changed the names to be the same.  Now it is easier to find the relevant policy referred to in a recommendation and enable/disable it.

For example:

Old policy name: Audit external accounts with write permissions on a subscription

Old recommendation name: Remove external accounts with write permissions from your subscription

Now – both policy and recommendation names: External accounts with write permissions should be removed from your subscription

This has no effect on the actual feature functionalities
