dotnet tool restore should provide warnings if new versions of tool is available #50991
Description
Is your feature request related to a problem? Please describe.
Our CI stopped working as tool needed an old version of SDK (6), which was removed from VM, but tool was on an old version in our .config/dotnet-tools.json... however a new version of the tool was available which worked as-is, but we didn't know at first that this was an option.
Describe the solution you'd like
It'd be great when running dotnet tool restore that if new versions of tools are available, that a warning is outputted to the console which specifies the latest version number.
Even better if there's a way to auto-update the config to use the latest version of all tools in it locally.
