POSIX sh support

[emersion]

Would be nice to have POSIX sh support instead of just Bash. Would allow people to use zoxide on a wide variety of shells.

The Bash init script doesn't seem too far from being POSIX.

ShellCheck reports the following:

In posixify line 16:
        result="$(zoxide query $@)" || return "$?"
                               ^-- SC2068: Double quote array expansions to avoid re-splitting elements.


In posixify line 19:
                _z_cd "${result:7}" || return "$?"
                       ^---------^ SC2039: In POSIX sh, string indexing is undefined.

Is this all that's necessary, or is there more that it missed?
