Publish extensions to Adobe Marketplace via EQP API

[amenk]

user story:

As an extension developer I want to automatically publish my extension updates (no need for the initial listing) to the Adobe Marketplace.

There seems an API for this:

https://developer.adobe.com/commerce/marketplace/guides/eqp/v1/#

If there are any other automatic solutions yet we shoud explore those, too.

Unfortunately the sandbox endpoint needed for developing such an integrations seems to be only available for bronze partners and up.

We are now generating the necessary ZIP and docs, that's a start.

But did not yet try to publish to the API, also because we do not have access to the test API.
