Use the language icon from https://languageicon.org for the language selector button

The language icon is great and we should use it.

The svg can be downloaded directly by clicking this link, and the code to use it is:

<img src="path/to/language-icon.svg" alt="Select Language">

They also offer other formats:

• png: https://languageicon.org/language-icon.png
• zip with all available formats, including .eps and .ai: https://languageicon.org/language-icon.zip

TODO:

• Download the svg icon to our project's assets dir
• Use it in the dropdown
