Use multiple integrity attributes for require.min.js

We observed that VS Code and Chrome each compute different integrity values. This is apparently expected behavior in some cases: https://claude.ai/share/7c3437d9-664e-4e82-aa92-6bdf37ff9025

Possible mitigations include:

1) Define multiple values for `integrity` (what we did here); or
2) Remove the `integrity` attribute if you trust the host and are running over https.
3) Bundle our own version of require.js
