Adding amplitude events for update school dialog

[hannahbergam]

Adds four amplitude events for the school info update dialog, as spelled out in product spec linked below, plus one added from PR feedback.

I also updated the a11y of this component to make it tab navigable by removing the __useDeprecatedTag. I had to update the styling of the update button: see before and after below.
Shoutout to @wilkie who translated this Storybook last year, which made development here much much faster! So fun to see the fruits of that labor!

To be clear: this is only the first portion of Amplitude work: there is a dialog that follows this if a user presses 'update' that is not yet instrumented.

Before:

After (excuse the active blue outline on the 'x'- this was just me testing out tabnav):

(This is how it looks RTL:)
