Support for this PR was originally articulated by @marler8997 as a // TODO on line 83.

This PR proposes a rather minor change to effectively extend the current functionality of the two existing CLI options (--install-dir and --path-link) such that they now will automatically inherit their values from environment variables (ZIG_INSTALL_DIR and ZIG_PATH_LINK, respectively). Documentation (via the help message zigup -h) was updated accordingly.

I discovered an issue with ZIG_PATH_LINK. One moment.

Disregard. It was a non-issue.
