Easily install common themes

[simison]

Especially when mass testing themes (https://github.com/simison/back-to-the-theme/), it would be neat to be able to install a whole lot of popular themes in one click. Boom!

Here's a nice list:

wp theme install \
	astra \
	colormag \
	customizr \
	generatepress \
	hestia \
	hueman \
	oceanwp \
	shapely \
	storefront \
	sydney \
	twentyeleven \
	twentyfifteen \
	twentyfourteen \
	twentynineteen \
	twentyseventeen \
	twentysixteen \
	twentyten \
	twentythirteen \
	twentytwelve \
	vantage

I briefly looked into this and I think a quick fix would be to enhance the following section:

jurassic.ninja/features/themes.php

Lines 19 to 21 in c40015b

	$allowlist = array(
	'tt1-blocks' => 'FSE: 2021 but with Blocks',
	);

While this does not install all themes with one click, it allows that desired themes can be selected.
