Add Claranet Italy and remove Flowing from the list

[ZarakiKanzaki]

Hi! I wanted to suggest the inclusion of Claranet Italy, currently the company has acquired Flowing and the old xpeppers. The tech stack had also changed a lot through the last year.
If you need any further information don't hesitate to contact me.
