$PATH is set before $HOME

Thank you for providing these images <3

In /etc/environment you have

/snap/bin:$HOME/.local/bin:/opt/pipx_bin:$HOME/.cargo/bin:$HOME/.config/composer/vendor/bin:$HOME/.dotnet/tools:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin

But this is too early. $HOME isn't set yet, so if you do echo $PATH you'll notice it contains literally the string '$HOME'. As a result, rust/cargo appear as not installed, I assume .dotnet would as well.

Fix: I moved those to /home/runner/.bashrc instead.
