sign-out issue on staging related to turbo that throws a CORS error (Access-Control-Allow-Origin).

Fix whatever is causing the signout redirect on staging not to work

The train of thought here is that these are firing as turbo_streams instead of full html reloads and this means they don't have the necessary information in the headers, which then causes the CORS error.

And because these were link_to instead of button_to, adding turbo = false did not work. It still processed as a turbo_stream. Documentation of it can be found in this issue.
hotwired/turbo#119

After fixing this, then we ran into some issues with the removed custom CompetitionsIdpEntityIdReader which needs to be added back.

The issue with the CORS error and needing turbo=false can be found discussed on these two blog posts.
