Subject: [PATCH] Replace <PackageLicenseFile> with <PackageLicenseExpression>

Because an embedded license file is used instead of an SPDX tag, automated tools like [nuget-license](https://github.com/tomchavakis/nuget-license) and [packageguard](https://github.com/dennisdoomen/packageguard) are unable to detect this package's license. Also the license does not show up in the package's metadata in nuget.

[Packing a license expression or a license file
](https://learn.microsoft.com/en-us/nuget/reference/msbuild-targets#packing-a-license-expression-or-a-license-file) recommends that MIT-licensed packages should have `<PackageLicenseExpression>MIT</PackageLicenseExpression>` instead of referring to a file.

The `License.md` file can still remain in the package, just the metadata would change.
