Special icon for external links

[shurup]

Most of the links we have now in the Glossary articles are internal, i.e. leading to other Glossary articles, thanks to interlinking all terms praised by the style guide. However, there might exist some external links as well. E.g., we have a link to the OCI website in the Containerization article:

I guess that most users won't expect to be sent to another website when clicking on such a link — since they get used to mostly internal linking across the Glossary. Thus, I suggest adding a special icon for all external links to tell users this link is external.

@shurup Thank you for your suggestion, and it LGTM.
I googled to find how to achieve this, and found these:
