Fix tooltip behavior in navigation sidebar

Summary

Tooltips are appearing at different intervals and interfering with moving around the navigation.

Steps to reproduce

Hover over buttons that have a corresponding tooltip

What is the current bug behavior?

a tooltip has a default delay of 500ms on show to help confirm hover intent and ensure that:

• A user doesn’t accidentally hover an element with a tooltip, which might cover an adjacent element they intended to select.
• The UI isn't constantly showing tooltips when a user is moving their mouse over the page. Pajamas

• Tooltips are appearing instantly and can interfere when trying to move to elements nearby or behind a tooltip

What is the expected correct behavior?

• All tooltips should take 500ms to appear
• Tooltips should be non-interactive making it easier to jump to elements behind a tooltip
