Revert "Update SDK (#46919)"

[mitchdenny]

Reverting SDK version due to CI build failures:

Processing binlog D:\a\_work\1\s/artifacts/log/Release/Build.binlog into solution at directory D:\a\_work\1\a/sourceIndex/
Unhandled exception. System.NotSupportedException: Unsupported log file format. Latest supported version is 15, the log file has version 16.

Last time this happened we needed to do this:

#45982

However it can take a few days to get the package updated in the feed, hence the revert.

Force-merging to get official builds working

Hopefully we don't need to revert EF as well ;)

Hi @mitchdenny. It looks like you just commented on a closed PR. The team will most probably miss it. If you'd like to bring something important up to their attention, consider filing a new issue and add enough details to build context.
