Add locations and number of countries to team page

I added locations for everyone on the team, based on Sundial (https://sundial.teleport.org/public/map/Y3IahPR5vYjBpMyU2kZj) or a quick Google search. Looks like we're at a whopping 26 countries right now, and that's excluding the people joining in the next few weeks. (The screenshot below is wrong, off-by-one error)

The only location I couldn't find was Ian's. @uid0 Would you mind adding your location to the team page yourself?

Some others I wasn't completely sure about, so I encourage everyone who comes across this MR to double check!
