Update "insufficient storage" conditon

[marcellamaki]

The banner that displays on a LOD when a user sync status is "Insufficient Storage" should only appear on Learn. Currently, it displaying also in the Device plugin, as seen below.

Because the StorageNotificationBanner is widely used and exists in core, this should not be moved (i.e. moving the component itself only to Learn), but rather, the condition should be updated.
(After further discussion, updated)
We should remove the banner from the AppBarPage, and instead put it into the relevant place in the Learn page

The banner:

• should appear in Learn when the status is INSUFFICIENT_STORAGE
• should be dismissed after a user clicks "manage channels" and is redirected
• the banner should not ever appear in the Device plugin, even if the user's status changes to INSUFFICIENT_STORAGE while they are in the Device Plugin

(While not a release blocker, this is an important change that we are prioritizing. This is open for community contribution, but contributors interested in this issue should only volunteer if they will be available to work on it promptly.)

Thanks @FidalMathew and @shivansh-bhatnagar18 for volunteering. It seems @iskipu already has a PR for that. Thanks @iskipu, and also would you mind asking for an assignment before working on something next time? Please have a look at contributing guidelines. It will always take us some time to respond to all comments we're receiving on issues, and it'd help us to distribute work.
