Update the CSP header for copi.owasp.org to include` form-action 'self'`.

Update the CSP header for copi.owasp.org to include form-action 'self'.
This restricts form submissions to only be sent back to its own origin.

Updated Header Example:

Content-Security-Policy: default-src 'self'; base-uri 'self'; frame-ancestors 'self'; form-action 'self'; script-src 'self'; style-src 'self' 'unsafe-inline'; img-src 'self'; connect-src 'self'; frame-src 'self'; font-src 'self'; media-src 'self'; object-src 'self'; manifest-src 'self'; worker-src 'self';

To fix this, you might have to create a new plug (NB: incomplete example):

pipeline :browser do

  # imports ...
  # header
  plug :put_secure_browser_headers, %{
    "content-security-policy" => "default-src 'self'; base-uri 'self'; frame-ancestors 'self'; form-action 'self'; script-src 'self'; style-src 'self' 'unsafe-inline'; img-src 'self'; connect-src 'self'; frame-src 'self'; font-src 'self'; media-src 'self'; object-src 'self'; manifest-src 'self'; worker-src 'self';"
  }
end
