Can't install tool with version containing a capital letter on Linux

[svick]

Describe the bug

If you try to install a .Net tool with version number that contains a capital on Linux, it fails with:

The settings file in the tool's NuGet package is invalid: Failed to retrieve tool configuration: Could not find a part of the path '/home/petro/.dotnet/tools/.store/dotnetsay/2.1.8-capital/dotnetsay/2.1.8-Capital/tools/netcoreapp2.1/any/DotnetToolSettings.xml'.
Tool 'dotnetsay' failed to install. Contact the tool author for assistance.

To Reproduce

0. Be on Linux.

1. Clone dotnetsay.

2. Change the version in .csproj to (it's important that VersionSuffix contains a capital letter):

   <VersionPrefix>2.1.8</VersionPrefix>
   <VersionSuffix>Capital</VersionSuffix>

3. Run dotnet pack /p:ContinuousIntegrationBuild=true.

4. Run dotnet tool install -g dotnetsay --prerelease --add-source bin/Debug/.

Further technical details

This behavior happens on the dotnet/sdk:7.0 Docker image, and also on Ubuntu 22.04 with .Net SDK 7.0.305 installed

We changed the implementation of tool install and restore in .NET 8. We will need to verify to see if the error still reproduces.

I tried this with net8.0 just now (on Ubuntu) and got a different error, but it seems like it's the same bug:
