What type of PR is this?

/kind feature

What this PR does / why we need it:

This PR proposes replacing Rendertron with chromedp/chromedp in krel testgridshot.

Rendertron is a deprecated and archived project. The public service is no longer available; all requests are failing.

This means that we can't use krel testgridshot, but have to take screenshots of failing boards manually. This PR proposes replacing Rendertron with a library called chromedp which uses Google Chrome and Google Chrome DevTools Protocol to navigate and manipulate web pages.

There are some needed considerations for this PR, so please check the special notes section for more details.

Which issue(s) this PR fixes:

None

Special notes for your reviewer:

  • Since Rendertron is deprecated and archived, I think that we shouldn't try to host it ourselves as there's no support for it
  • There are still some flakes with this implementation that I need to look into, but I'm first trying to collect feedback if we want to proceed with this idea
  • This library requires Google Chrome. If we decide to proceed with this, I would look into making it possible to run this with Docker
    • I was looking into if there's a better library, but that's the best one I was able to find. If you have any ideas, please let me know

Does this PR introduce a user-facing change?

Fix `krel testgridshot` failing to take screenshots of Testgrid
