Fix wrong shell profile in install script message

[inteon]

fixes #93

It didn't work for me. I used nixery to create a container with zsh + curl + other tools, and it still printed out the bash install instructions....because there was no $SHELL environment variable.

How did you test this?

richard@LAPTOP-HJEQ9V9G:~$ docker run --rm -it nixery.dev/curl/gnutar/gzip/coreutils/zsh zsh -c 'curl -fsSL https://raw.githubusercontent.com/jetstack/jsctl/fix_typo_install_script/install.sh | zsh'
######################################################################## 100.0%
jsctl was installed successfully to //.jsctl/bin/jsctl

Manually add the directory to your $HOME/.bashrc (or similar)
  export JSCTL_INSTALL="//.jsctl"
  export PATH="$JSCTL_INSTALL/bin:$PATH"

And run "source //.bashrc" to update your current shell

Run '//.jsctl/bin/jsctl --help' to get started

@wallrj This issue should be fixed now.

Thanks.
I retested and could see it working.

docker run --rm -it nixery.dev/curl/gnutar/gzip/coreutils/zsh zsh -c 'export HOME=/tmp; curl -fsSL https://raw.githubusercontent.com/jetstack/jsctl/fix_typo_install_script/install.sh | zsh; echo export JSCTL_INSTALL="/tmp/.jsctl" >> /tmp/.zshrc; echo export PATH="$JSCTL_INSTALL/bin:$PATH" >> /tmp/.zshrc; source /tmp/.zshrc; cat /tmp/.zshrc; jsctl '
