Context:
In Saas, we would like to keep the navbar help and info links consistent with the other products.

AT:

• Add missing help links to make it consistent with the other products
• Update the text of the existing links to be consistent with the other products

Testing Notes:

• After logging in, open the Optimize user menu from the navigation
• You should see the following links:
  • Telemetry Settings
  • Terms of Use
  • Privacy Policy
  • Imprint
• Open the info menu from the navigation and you should see the following links:
  • What's new
  • User guide
  • Camunda Academy
  • Feedback and support
  • Slack Community

All Links should work and go to the correct page.
