Change language picker icon

[ArkinSolomon]

Fixes #3372. I know this had 2 pull requests created already, with the most recent one dying pretty quickly. It was a pretty simple change to use the new image. I did slightly modify the icon to be white only. It works fine for both light and dark modes.

Where did the icon come from originally?

[ArkinSolomon]

It came from http://www.languageicon.org/, see #3503.

It shouldn't be a PNG.

Please use SVG files after optimizing it and no redundant attributes.

[ArkinSolomon]

I have changed the icons to an svg by converting it from .eps, and manually added light and dark variants and used css to change them when the theme changes.

LGTM

Is this PR good for merging @XhmikosR ?

[XhmikosR]

Sorry, I can't review the result (this is one of the cases PR previews would go a long way).

If someone can confirm everything looks good on both themes, that's good enough from my side judging by the code changes.

@XhmikosR If you're online right now, here's a preview I'll keep around for the next 30 minutes or so: https://8080-arkinsolomon-nodejsorg-yges5368tg1.ws-us38.gitpod.io/

Thanks @Trott!

Confirmed LGTM. The same optimizations could be made to the dark switcher icons later (inline them, optimize them, toggle the d-none class etc)
