Fix Rails version compatibility for content_security_policy_nonce

The content_security_policy_nonce helper has different signatures across Rails versions:
- Rails 5.2-6.0: content_security_policy_nonce (no arguments)
- Rails 6.1+: content_security_policy_nonce(directive) (optional argument)

This change adds a try-catch to handle both versions gracefully.

Fixes CI failures with "wrong number of arguments (given 1, expected 0)".
