EDSC-2672: Lazy load Timeline component

[mreese84]

Description

In an effort to improve initial load times, we should lazy load the Timeline component. We want to be sure to do this in a way that does not degrade the UX of the initial application load.

Acceptance Criteria

• Timeline javascript is only loaded in pages that render the timeline (/search/granules, /project)

Hi @mreese84 I need to take a closer look at the codebase but I think this could be accomplished with React.suspense https://web.dev/code-splitting-suspense/

If this is the case I can work on this issue 🙂

@sofiarivas, thats correct! We have React lazy/suspense implemented in a few other places throughout the application if you would like some prior art.

At first look, it seems like this could be implemented in the TimelineContainer component.
