Bring screencaps and graph images on website up to date

[merobi-hub]

Problem

With the release of 0.45.0, the images currently used on the website will be out of date.

Solution

This makes the images current while a larger-scale redesign of the site is undertaken, so that users have an accurate sense of Marquez immediately.

Note: All database schema changes require discussion. Please link the issue for context.

One-line summary: Updates images on website.

I also created a white version of the main logo in case that, with or without green buttons, is preferable. (Note: the screenshot here is out of date.)

[phixMe]

I think we would want to avoid cropping the browser bar if we indeed want to go with photos.

[merobi-hub]

@phixMe which photos are you referencing re the browser bar? The two inner ones in the logo section?

[phixMe]

Just the way this cropped.

[merobi-hub]

@phixMe the browser bars are not visible for me unless I'm scrolling, so I made new screencaps without the scrollbar in any of the images. Also, I went with 2 instead of 3 screenshots so more detail is visible and used SVGs of whole-window screencaps for more precision and uniformity.
