[sql] Workaround integration test failures

[CodeBlanch]

It seems latest/current Testcontainers.MsSql version isn't compatible with GitHub runners which were pushed out. This PR manually sets the image version temporarily so things will work. Also looks like the SqlEdge package has been completely deprecated. We're not currently running that in our CI but we might start if ARM gets introduced.

For details see: testcontainers/testcontainers-dotnet#1265
