[Eng]: sync more files from main to generation branch

[isra-fel]

Description

We have a pipeline azure-powershell - sync-tools-folder to sync files which are necessary for building on both main and generation branch. However src/Az.props and src/shared/* (introduced by #18162) are not on the list of files to sync. This caused CI errors.

Excpeted

src/Az.props and src/shared/ can be sync by the pipeline.
