Fix students context menu

Fixes #6123

Changes proposed in this Pull Request

• Previously, I tried to update wp-components to a newer version, but that caused a lot of other problems.
• Now I'm just using Good Ol' CSS to make it appear.
• I tested in WP 5.9.5, 6.0.3, 6.1, and 6.1.1 and it looked good in each.

Testing instructions

• Go to Sensei -> Students
• Click the ... menu
• Make sure it opens up

@Imran92 - thanks for your suggestion, I've fixed it in d97fe51

One issue I found is that on mobile the menu is not visible:

I've tried looking at z-index and the stacking order but can't seem to figure out yet why it's always hidden behind. Any ideas on what to do here? Thanks!

Edit: @renatho helped me with this one and I've pushed a fix for mobile screens as well :)

LGTM 👍
