Update installation instructions wrt install dir?

[jbclements]

The installation directions suggest that the agda library information directory lives at $HOME/.agda/libraries. However, the documentation at https://agda.readthedocs.io/en/latest/tools/package-system.html suggests that this is out of date (though still supported), and suggests identifying the location using agda --print-agda-app-dir ... which indeed, on my macOS system, returns $HOME/.config/agda rather than $HOME/.agda. So perhaps the installation directions here are out of date? Or perhaps there should just be a link to the readthedocs.io site?

Apologies if I'm wading into a religious debate that I'm not aware of :).

While I'm looking at this page, it looks like the command-line comment

wget -O agda-stdlib.tar https://github.com/agda/agda-stdlib/archive/v2.1.1.tar.gz

... should instead be

wget -O agda-stdlib.tar.gz https://github.com/agda/agda-stdlib/archive/v2.1.1.tar.gz

, and the later command

tar -zxvf agda-stdlib.tar

should instead be

tar -zxvf agda-stdlib.tar.gz

Granted, the current pair of commands works, but it's giving a .tar suffix to something that is definitely not just a tar file, but instead a gzipped tar file.

... and naturally, if you prefer tgz well then that sounds perfect as well!

Yes, those both seem reasonable changes to make. Thanks for spotting! Would you be willing to make a PR fixing it?
