Multiple OSPO Stories in the menu

From Nicolas Toussaint in the mailing list:

Sebastien's testimony can be found from the menu About us → OSPO Stories But in Resources, there is also a section OSPO Stories with the RampUp sessions (including Sébastien's from April 2023)

I think the same naming, OSPO Stories, in different places with similar contents (though different forms) can be a bit confusing

A simple proposition would be to rename About us -> OSPO Stories as About us → Testimonies

Otherwise, we could rethink the Resources page to include everything there, but that's much more work (and not so convincing imo)
