Exit on error

[coffeejunk]

If any of the (sub)commands in install.sh fail, the install script will continue to run and effectively hide the fact that something went wrong. Setting set -e will make the bash script exit upon an error.

Context: I was just testing #29 in an arm64 VM, and the installation of mise failed silently (because the current version does not have a code path for arm64); however, it appeared as if the installation had worked correctly and I got logged out at the end of it.
Then, when I tried to log in again, the system would simply hang. Upon further inspection, I realized it was hanging on this prompt:

omakub/defaults/bash/init

Line 4 in 9c603cd

gum confirm "You're missing mise (replacement for rbenv + nodenv). Install now?" && \

I think this is a great catch and I think a great implementation and use of the command, btw the issue in #29 should be fixed

Yes, this makes for a very important addition.
