ProjInfo 0.62.0's tool cannot load 8.x projects

[baronfel]

Describe the bug
The tool bundled copies of Microsoft.Build and Microsoft.Build.Framework assemblies in it and as a result doesn't load the versions from the SDK on-disk.

To Reproduce
Steps to reproduce the behaviour:

1. Install 0.62.0 globally
2. run proj-info --project <project>
3. Get an exception
4. Navigate to <tools install dir>/.store\ionide.projinfo.tool\0.62.0\ionide.projinfo.tool\0.62.0\tools\net7.0\any and delete Microsoft.Build.dll and Microsoft.Build.Framework.dll from that directory
5. Re-run proj-info --project <project>
6. Get the parsed project
