CmdPal: recommend extension developers to to also add a winget package

Description of the new feature / enhancement

The official documentation on how to publish an extension indicates the recommended way is to publish to the microsoft store.
As a result, most extension are only available via the store with no other way to install them.
The issue is many organisation disable access to the microsoft store, but winget still works as packages are usually hosted on github instead of a microsoft store server.
This results in a lot of extensions that I (and probably many other users) cannot use, all because of a single word on a web page.

This page should be reworded to recommend publishing to both channels.
This is also inconistent with the Publish to Winget page that states publishing to winget is the recommended distribution method ...

Also please see #47076 and #38273 as it seems following these instructions produces installers that don't work with the command palette (extension not discovered).

Scenario when this would be used?

Any corporate network where access to the microsoft store servers are disabled

Start with the linked Publish extension and Publish to Winget documentation pages and compare their distribution recommendations. Reword the extension publishing guidance to recommend both Microsoft Store and winget, while keeping it consistent with the winget page; verify that the related installation concerns in #47076 and #38273 are not contradicted.
