Add new screenshot for Basis with Hero image introduced in Backdrop 1.30

[olafgrabienski]

I'd like to suggest that we show the new wavy hero SVG image in the screenshot.png of the Basis theme.

The SVG hero image was introduced in Backdrop 1.30.0, issue #6752. There was a similar case when we changed the screenshot after introducing the Home page cards, see #5621.

Current screenshot:

New screenshot proposal:

The image dimensions are 600 x 416px. On the Theme admin page, the screenshot is scaled down to a width of 294px.

@olafgrabienski counting the "thumbs up" on the issue description - I guess there's consensus. 😉 We're just waiting for a PR.

@indigoxela It seems I need some help in this particular case. I use to make pull requests via the Github interface, as described in https://backdropcms.org/news/creating-pull-requests-against-core-the-easy-noob-way. It's not clear to me, how I can replace a (binary) file in this scenario. If this isn't possible or rather complicated using the Github interface, I'd be happy if someone else could take over.

@olafgrabienski I'm afraid, I'm the wrong person to ask such a question. I never work with the GH code interface, always only with commandline.

But it seems like @izmeez helps out with a PR. 👍 Looks good!

I see, no problem!

Great, thanks @izmeez for taking over. I've had a look at the sandbox of the PR: the appearance page with the screenshot looks perfect.
