Scientific domains enhancement

[maharshi-gor]

• What kind of change does this PR introduce? (Bug fix, feature, docs update, ...)

• This PR introduces the feature that on hovering the scientific domain, the popup with the animated gif will appear in the home page of the fury website

• What is the current behavior? (You can also link to an open issue here)

• No effect on hover.

• What is the new behavior (if this is a feature change)?

• It will open up a popup.

• The popup can be closed in two ways

  1. By hovering out of the popup
  2. By clicking outside of the popup

• Other information:

• The animations in the popup are modified a little bit from the original tutorials.

• The animation for the data-science field is created from a newly created example(which will be pushed in upcoming PRs).
