[BUG] Discrepancy on model size

[KenjiBaheux]

Bug Description

Hi,

I've noted the mention of 22GB in various places (UX, documentation, etc), and in some cases I imagine that your users might assume that the download / model itself will occupy 22GB.

In practice, while Chrome requires at least 22GB of free space, it only uses a couple of GB for the model. This margin is to avoid putting a disk in low storage pressure mode.

Would it be possible to adjust the wording or the number to minimize confusion?

Thanks for building this extension with the Proofreader API!
PS: I'm the product manager for it, and would love to hear your feedback.
