Major flaw in PATH handling of install.sh

[Arcitec]

The latest version of install.sh creates the PATH as follows, which breaks every user's system if they have any paths with spaces:

export PATH=~/.pixi:$PATH

The correct method is to always, always, always double-quote:

export PATH="~/.pixi:$PATH"

Furthermore, you should either be resolving the ~ or replacing it with $HOME, because ~ is not valid inside PATH. So the final code would be:

export PATH="$HOME/.pixi:$PATH"

Thanks @Arcitec - the code for install.sh is right here: https://github.com/prefix-dev/pixi/blob/main/install/install.sh

Do you want to send a PR?

Here's an example of every other software's PATH handling from my own .zshrc:

@wolfv I was considering making a PR but I see that you support many shells, so I am not 100% comfortable doing it since I could only test Bash and ZSH.

[Arcitec]

@wolfv I suppose I could do the Bash and ZSH parts now.

Yes, that would already cover many users! Thank you 🙏
