Remove extra spaces in Publishing.props

[premun]

This removes some extraneous whitespace characters introduced in #6233.
The VMR synchronization has problems with these thanks to the CRLF in this repo and we are unable to remove a patch for this in dotnet/sdk#46361

@ViktorHofer @mmitche @NikolaMilosavljevic this fixes the VMR synchronization issues from dotnet/sdk#46361

[premun]

@jeffkl can you help us merge this please?

[mmitche]

@premun Is there a longer term fix that we can do on the Maestro side?

[premun]

Possibly. I think this started happening with newer git as I cannot reproduce it on a similar Linux image with older one.
I think it's something about how git handles whitespace during patch creation/application. But it might be quite risky. It might be possibly only the combination of a VMR patch + a change + patch removal.

I've enable auto-merged for this since it's the infra issues might be blocking .NET 10 P1.

It's already running, I kicked that off.

@premun do you need another code flow from NuGet to fix dotnet/sdk#46361?
Is there any way it can be unblocked without this PR?

[premun]

If we can have another code flow, it would be great as I am at the end of my working day.

Or we can try creating a patch from this PR and adding it to dotnet/sdk#46361 - it might just work
