[ZEPPELIN-1912] fix: Improve perosnalized mode tooltip text

[1ambda]

What is this PR for?

Currently the tooltip for personalized mode is quite confusing. Since

• tooltip text is {{Collaboration mode}}
• and when i click the icon, dialog tell me {{Do you want to personalized your analysis?}}

Tooltips should tell us what we can do instead of just stating current state as other tooltips do

What type of PR is it?
