Updates to existing Governance Guidance

One image removed (no longer relevant). Adjustments to comments based
on feedback from content initially published. Content written by Governance team and content designed by Beck Thompson
Our content designer was OK with 'empowered' but isn't around to comment. How about 'the service manager and team have the authority to make informed decisions promptly so that they rarely need to escalate'.?

Also, there's a further use of empowered in principle 3. I'm definitely reluctant to change that in the absence of our content designer.
