Untangle Media: Simplify upsell message

[jameskoster]

The upsell messaging here is unnecessarily verbose. Let's explore a lighter or more nuanced approach.

Option 1

Here's a very basic idea that would reduce from two lines to one:

Option 2

A more comprehensive solution could be to conditionally show the upsell messages. For instance we might only show the storage details / upsell when a certain threshold is breached:

Additionally we might show the file format upgrade nudge only if the user tries to drop a video or audio file on the dropzone:

This would eliminate the nagging sensation caused by the ubiquitous 'upgrade' messages throughout the experience (related: #96875).

I'm taking a look... I'll also incorporate some concerns about verbose messaging raised in Automattic/jetpack#41089. cc @arthur791004

Proposing 172488-ghe-Automattic/wpcom which implements Option 1.
