[SDK] Not Updated Alongside Element App

[shining-grimace]

Description

Hi, and thanks for all the ongoing work going into Element Android.

Regarding the SDK in the matrix-android-sdk2 repo, it hasn't received updates in quite a while now.

To quote the readme file for element-android repo, "at each Element release, the SDK module is copied to a dedicated repository ... third party apps can add a regular gradle dependency to use it." And the release checklist on release issues such as #8984 includes this process but seemingly isn't adhered to.

Will the SDK be updated still in its repository (and on Maven), or are the readme file and release checklist wrong and users of the SDK need to find another way to get recent updates?
