System.Memory is not referenced in the built nuspec despite being referenced in the Assembled dll

[BryanAldrich]

Bug description

The nuspec file in the nuget package is missing the System.Memory dependancy for .net framework 4.7.2 This is causing the package dependency graph for nuget to fail if system.memory isn't manually installed and bumped up to 4.5.5 from what otherwise would be 4.5.4

.NETFramework 4.7.2
Microsoft.Bcl.AsyncInterfaces (>= 7.0.0)
Microsoft.VisualStudio.Threading.Analyzers (>= 17.9.28)
Microsoft.VisualStudio.Validation (>= 17.8.8)
Microsoft.Win32.Registry (>= 5.0.0)
System.Runtime.CompilerServices.Unsafe (>= 6.0.0)
System.Threading.Tasks.Extensions (>= 4.5.4)
.NETStandard 2.0
Microsoft.Bcl.AsyncInterfaces (>= 7.0.0)
Microsoft.VisualStudio.Threading.Analyzers (>= 17.9.28)
Microsoft.VisualStudio.Validation (>= 17.8.8)
Microsoft.Win32.Registry (>= 5.0.0)
System.Memory (>= 4.5.5)
System.Runtime.CompilerServices.Unsafe (>= 6.0.0)
System.Threading.Tasks.Extensions (>= 4.5.4)

Repro steps

See attached.

The issue isn't caused by Nito, just happened to be the other package in my scenario. It appears to actually be caused by the System.Collections.Immutable reference.

Expected behavior

Nuget package graph to include 4.5.5 for System.Memory

Actual behavior

Big warning.

Thank you for reporting this.
This appears to be due to microsoft/CsWin32#1158, which was recently fixed, and should be applied to this repo.
