`dotnet list package` fails when current directory path contains `#` character

When running dotnet list package while in the directory of a project with a # character in its path, I get the following error:

% pwd
/Users/allan/C#
% dotnet list package
Could not find file or directory '/Users/allan/C'.
...

This works fine when the path doesn’t contain a # character, or if I specify the project name in the command:

% dotnet list Test.csproj package
Project 'Test' has the following package references
   [net5.0]: No packages were found for this framework.

Steps to reproduce

1. Create a folder called C# and cd into it.
2. Create a new project (e.g. dotnet new console -n Test -o .)
3. Run dotnet list package and observe the issue described above.

Other observations

• dotnet list reference doesn’t seem to have this issue.
• Paths with other special characters may also be affected.

I suspect the bug is in PathUtility.GetAbsolutePath, which uses the Uri class even though the input is not URI-encoded: https://github.com/dotnet/sdk/blob/e9667aef50fe25c58ea4310ec42a62a5e8813283/src/Cli/Microsoft.DotNet.Cli.Utils/PathUtility.cs#L237-L238

It is called from the ListPackageReferencesCommand constructor:
