Installation is broken with older (<1.0) rlang versions

[pettyalex]

Hello,

A few of my team ran into this and lost some time today, it looks like patchwork depends on on_load being exposed from the package rlang, but that function was only added in rlang 1.0. We all had rlang 0.4.4 installed, and because patchwork doesn't specify that it requires 1.0 or greater it tries to use old rlang, and fails.

This should be an easy fix: specify rlang >= 1.0.0.

The failure looks something like this:
