Add appending to PATH instruction inside installation script

[Hennzau]

Hi! The installation script introduced in #600 is excellent! I think most beginners really need something easy to execute, especially students.

I changed the final message to provide more useful instructions for appending directly to .bashrc or .zshrc, so the Dora CLI is now accessible everywhere, every time, without needing to source your path again and again when you change your terminal.

Here’s how it looks for ZSH:

echo 'export PATH=\$PATH:$dest' >> ~/.zshrc
source ~/.zshrc

Of course the user can decide to not append his path.

Indeed, that's very useful! Thanks!

FYI, I made the script so that we can not only install dora-cli but also any binary given a github repo.

In the future we could release rust node using a predefined naming and people will be to curl install it without having to have cargo installed. This will also make it easier for people with exotic target such as raspberry-pi macos windows...
