📌 Summary

If merged, this PR will make a change to the code editor to allow a cspNonce property to either be automatically pulled from the consuming app's content security policy, or passed directly to the component.

🛠️ Detailed description

Some consuming applications have strict content security policies against dynamic style tag insertion. A way around this is to add a nonce to both the content security policy and any injected style tags. CodeMirror 6 supports this functionality through a cspNonce attribute.

This PR:

• Exposes the cspNonce setting to the code editor api
• Will automatically try to pull the nonce from the security policy
