dotnet tool install --global reinstalls even if the same version is already present

[rozumak]

Describe the bug

dotnet tool install --global reinstalls even if the same version is already installed. But it should ignore it as in previous .NET SDK versions. This behavior was probably introduced in #37311. This causes the folder with the installed tool to be cleaned up every time dotnet tool install is called from a build script. Previously, this step was failing. Probably there are some workarounds to keep the previous behavior?

To Reproduce

Run dotnet tool install --global tailwindcss-dotnet --version 1.0.0 when this tool is already installed.
To ensure that it tries to reinstall, just open the folder where this tool is installed: C:\Users\user\.dotnet\tools\.store\tailwindcss-dotnet\1.0.0\tailwindcss-dotnet\1.0.0 in explorer to lock the folder. In that case, it says:

Tool 'tailwindcss-dotnet' failed to update due to the following:
Failed to uninstall tool package 'tailwindcss-dotnet': Access to the path 'C:\Users\user\.dotnet\tools\.store\tailwindcss-dotnet\1.0.0' is denied.

@nagilson, this sounds like a recent regression that we probably want to look into. Assigning to you as the resident dotnet-tool expert.
