Linux: Installing/Updating packages with uppercase versions

[edvilme]

Addresses #39105 #24419 #41844, https://github.com/NuGet/Home/issues/13844, etc

When attempting to install or update a tool on Linux, the system looks for the file with the version as is, instead of lowercasing it. Packages are ideally stored with lowercase versions on them according to the NuGet team, so the system fails to find them.

Instead, versions are lowercased and the VersionFolderPathResolver API is used for path operations to be compliant with changes from the NuGet codebase.
