Adds a configuration to rename the CSP helper attribute name to avoid value exfiltration as described in #51580 (comment)
It's disabled by default currently until the JS libraries are updated to the new attribute name and Rails can ship with a new default attribute name.
Fixes the Rails part #51580. See this PR for a potential fix in Turbo: https://github.com/hotwired/turbo/pull/1254/files
If this approach makes sense in general, I'd try to fix ujs as well 👍
