Improve logo for VS Code K8s Tools

[bridgetkromhout]

Hi, folks -

I noticed that there is no easy way to notice that VS Code K8s Tools is on the CNCF Sandbox page, because it has a generic CNCF logo that doesn't indicate its name. Until you hover over the item you won't know what it is, as seen in this screenshot:

The uninformative image in question is at https://github.com/cncf/landscape/blob/master/hosted_logos/vscodek8stools.svg and was uploaded to fill the gap of having no logo at all, in #3373.

The question for @mrbobbytables is, would you be able to replace https://github.com/cncf/landscape/blob/master/hosted_logos/vscodek8stools.svg with something like this?

That way, people would be able to find this project when they are looking on the website.

I realize that is not the same as having a logo, but I think it is an incremental improvement over the current lack of discoverability. (The lack of logo is mentioned in cncf/sandbox#181 (comment), and can be followed up there - I am trying to improve the website meanwhile.) Thanks for considering!
