feat(platform): Integrate new ai-bot solution in platform

[chargome]

Problem Statement

We want to integrate kapa.ai as our new vendor in docs.

• Remove docsbot
• Add kapa.ai widget (use existing button)
• Update CSP policy for re-captcha and kapa.ai scripts / css
• Add user docs and develop docs as allowed origins on kapa platform
• Add a button for opening kapa widget when algolia search returned no results

POC was handled in: #11647
