Showcase: Put game title in text too

[JohnVeness]

Hi again. On https://godotengine.org/showcase/ currently the game titles are only in the thumbnail graphic. Some of them can be tricky to read quickly (not necessarily picking on the ones below!), and you can't use Ctrl+F to search for the titles.

So, could the game title appear under the thumbnail along with the developer name, e.g.:

Madness/Endless
by Poke the Ant

A Most Extraordinary Gnome
by Save Sloth Studios

Endoparasitic
by Miziziziz

Dome Keeper
by Bippinbits

Adding the word "by" also make it clearer the name after it is of the developer, not the name of the game, which is not immediately obvious on the current site.
