Twenty Nineteen: Update theme description and tags

[kjellr]

The theme description currently in place for Twenty Nineteen was meant as a placeholder.

Twenty Nineteen is a Gutenberg-ready theme for WordPress.

This should be updated to the description that exists over on Twenty Nineteen's GitHub repo:

Our 2019 default theme is designed to show off the power of the block editor. It features custom styles for all the default blocks, and is built so that what you see in the editor looks like what you'll see on your website. Twenty Nineteen is designed to be adaptable to a wide range of websites, whether you’re running a photo blog, launching a new business, or supporting a non-profit. Featuring ample whitespace and modern sans-serif headlines paired with classic serif body text, it's built to be beautiful on all screen sizes.

In addition, the theme's tags are not consistent across readme.txt, style.css, and style-rtl.css. They need to sync up, and theme-options tag should be removed, since Twenty Nineteen does not utilize that customizer panel.

(This PR ports over the updates from Twenty Nineteen's GitHub repo: ​https://github.com/WordPress/twentynineteen/pull/710/ )

Thank you for porting this over, @kjellr!

Right now 45693.patch​ is failing for me in all but style-rtl.css:

I think it's just clashing with other minor changes in these files -- are you able to refresh this in the next day or so?

Removing needs-refresh -- I double-checked, and I can take care of cleaning up the patch before commit :)
