Doc update monitoring dashboard

What does this MR do?

This MR adds a section in the docs about the monitoring dashboard specifically to add a sentence about searchable environments dropdown. This update will help with the release post item.

Note I'll create another issue to update the docs about other dropdown controls.

@dbodicherla LGTM

I'm doing a review on the text now, but I see two sets of changes to make to the images:

1. Add _v12_8 to the image names so the TW team can tell at a glance in the future how old the images are (style guide source)
2. Run the images through pngquant to compress the file sizes. (It dropped one from 95K → 30K and the other from 25K → 7K)

I've attached the squished-and-renamed versions here for you to update your branch with, while I review the text.

I've added in my wording suggestion, and provided updated versions of the images. Unassigning myself; ping if you've got questions!
