@narasimhan-lakshmi thanks for tackling this change. I've left a suggestion for a couple of improvements.

Why revert back to 58? (accident?)
Users will need to use 140, otherwise it won't work during addon submission due to usage of new data_collection_permissions key:

No, they only need to set strict_min_version to 140 if they don't intend to provide a custom experience for early versions.

I've tested it now using web-ext lint command available in the web-ext tool.
If I set strict_min_version to 139 I get this warning:

It's very likely people will see this warning upon submission to the addons store.

When you run the extension on Firefox 139, it doesn't display the built-in data-collection dialog. Hence, the point of Data collection experience on older Firefox versions. Extensions that collect data covered by the extension policies and want to run on 139 or earlier have to add a custom dialog for data consent (or disable data collection).

I'm not talking about running Firefox, I'm only saying that submitting addon to the store with anything lower than 140 in the strict_min_version value will produce the warning above.
And using lower number and removing the data_collection_permissions will produce also a warning:

So the best way, that will not confuse new developers, is to use 140 and the data_collection_permissions as is in the example.
Only that will produce no warnings and everyone is happy :)
It's not like there is a reason to support anything below 140 anymore, right?

[rebloor]

The example is valid and can be used with any version of Firefox from 58 onward. Using the value of 140 could give the incorrect impression that data_collection_permissions can't be specified in extensions targeting versions before 140.
