allow targetting a specific sdk version when running dotnet format command

[krishna007-cloud]

dotnet format failing on warnings ever since dotnet version 9 installed.

The dotnet runtime version is '9.0.8'.
The dotnet CLI version is '8.0.413'.
Using MSBuild.exe located in 'C:\Program Files\dotnet\sdk\8.0.413'.

Could you advise as pinning the version using an env variable as not working.
