### Description

The instructions on for the .NET 10 installation on linux say to put decompress the download to $HOME/dotnet and the .NET 9 installation instructions say to put it in $HOME/.dotnet

.NET 10 Preview install
https://dotnet.microsoft.com/en-us/download/dotnet/thank-you/sdk-10.0.100-preview.6-linux-x64-binaries

> mkdir -p $HOME/dotnet && tar zxf dotnet-sdk-10.0.100-preview.6.25358.103-linux-x64.tar.gz -C $HOME/dotnet
export DOTNET_ROOT=$HOME/dotnet
export PATH=$PATH:$HOME/dotnet

.NET Scripted Install instructions

https://learn.microsoft.com/en-us/dotnet/core/install/linux-scripted-manual#example

> DOTNET_FILE=dotnet-sdk-9.0.100-linux-x64.tar.gz
export DOTNET_ROOT=$(pwd)/.dotnet
mkdir -p "$DOTNET_ROOT" && tar zxf "$DOTNET_FILE" -C "$DOTNET_ROOT"
export PATH=$PATH:$DOTNET_ROOT:$DOTNET_ROOT/tools

Having separate paths for DOTNET_ROOT doesn't allow the dotnet app to find the correct location and --list-sdks doesn't show all sdks.

### Workaround
Use $HOME/.dotnet for all of my installations.
