Change the slug url of open-cti-integrations for opencti-integrations

[EllynBsc]

Overall Description
For better SEO, we need to change the slug for "opencti-integrations" in the URL instead of "open-cti-integrations"? In the past, "open-cti" caused some issues with search engines on our website.

We also have these slugs :
open-cti-custom-dashboards
open-aev-scenarios
I imagine I rename them as well ? @EllynBsc
