#### Why I did it ISSU version check fails due to inability to mount squashfs from 202211 on 201911 #### How I did it Put ISSU version file under platform directory #### How to verify it Warm-upgrade matrix: - 201911 (with https://github.com/sonic-net/sonic-buildimage/pull/14928) to master - 201911 (with https://github.com/sonic-net/sonic-buildimage/pull/14928) to 202211 - 202012 (with https://github.com/sonic-net/sonic-buildimage/pull/14927) to master - 202205 (with this change cherry-picked) to master
