[OSPO Book] Improve the OSPO Flower

#603 from @Pizza-Ria

Chapter 3

Flower - I think someone already mentioned this but I'll +1 the add of security. Also "Internal Ecosystem" does not appear to be defined. Not sure if this was intended to include consumers of open sources in addition to the other petal "contributors". Might need something about engagement with Standards in here too.

Would need to ask someone @anajsana ? to help find the original image to be able to edit it.
