CA2022 error in src/Microsoft.Web.XmlTransform/XmlFileInfoDocument.cs

[NikolaMilosavljevic]

New SDK introduces new warnings that turn into errors in VMR build - see dotnet/installer#19145 (comment)

##[error]/vmr/src/xdt/src/Microsoft.Web.XmlTransform/XmlFileInfoDocument.cs(93,17): error CA2022: (NETCORE_ENGINEERING_TELEMETRY=Build) Avoid inexact read with 'System.IO.Stream.Read(byte[], int, int)' (https://learn.microsoft.com/dotnet/fundamentals/code-analysis/quality-rules/ca2022)

I'm going to patch to disable this warning, in VMR builds. However this needs to be properly fixed.
