Misleading snackbar message on page load fail retry

[develric]

Could not investigate the reason and/or if it can cover something more, but while looking into this Push Notifications PR I noticed the following

Expected behavior

When a page upload fails, we present a system notification. If user taps on the notification, the pages list is opened (while the page upload is being retried) and a snackbar is presented saying something like "Page upload retrying" or something similar.

Actual behavior

When a page upload fails, we present a system notification. If user taps on the notification, the pages list is opened (while the page upload is being retried) and a snackbar is presented saying "The selected page is not available"

Steps to reproduce the behavior

• Create a new page and force the upload fail (one way is using the Breakpoint feature of Charles Proxy configuring a breakpoint like this
  
  where is the site id of the site you are using to upload the page

• once the upload fail, notice the upload fail notification is shown
  

• tap on the notification and check you get the snackbar saying "The selected page is not available"

Tested on [Pixel 3 Emu], Android [API 29], WPAndroid [alpha-234]

I was able to reproduce this in WP Android 21.1-rc-2 on Samsung Galaxy S21, Android 12.
To reproduce on a physical device, I turned on airplane mode after tapping publish.

Here's that "The selected page is not available" snackbar:

The error messaging could definitely be more helpful here.
