[Bug] The Content-Security-Policy header must not be overridden

[sebbASF]

https://github.com/apache/skywalking-website/blob/2c07fa6a75d09f36460d022cc14b85f91625337f/.htaccess#L4

The Content-Security-Policy header must not be overridden.

There is now a standard way to add local exceptions to the CSP:

https://infra.apache.org/tools/csp.html

Please update the .htaccess file accordingly.

Please note that the policy says that any exceptions must have been approved, and a reference to the approval must be commented in the .htaccess file

@Jtrust is working on that. We will get feedback on this.
