[Cloud Security] Update copy for Agentless Setup Access instructions

[maxcold]

Motivation

As we added Agentless option for all cloud providers in CSMP, we need to make sure the texts on the "Add integration" page makes sense for Agentless too. Here is the current state of the texts

CSPM AWS

The texts were adjusted during the development, but were not confirmed by the product or documentation team

CSPM GCP

The texts are the same as in agent-based

CSPM Azure

The texts are the same as in agent-based

Definition of done

• [ ] Texts for Setup Access instructions are adopted for Agentless. We can have two sets of copy, no need to come with an universal one

Out of scope

• documentation update for agentless will be done in a separate task

@maxcold @tinnytintin10 Also, not sure if this ticket will contain instructions for Credentials Cloud Formation button. Updating the text to instruct user what they should do after clicking the Launch Cloudformation button. I found the UX transition from integration to AWS cloud formation Stack a little confusing. For instance, once I click Launch Cloudformation

• what should I do next?
• Is the stack the same as creating Agent-based formation stack?
• Where can I find the direct access keys once my stack is created?

wdyt?
