Fix typo in entrypoint.sh

[santilococo]

There is a typo in contexts/entrypoint.sh; it is missing a newline. Therefore, it won't add the [allowed_hosts] line, and the allowed_hosts{n} instructions won't be taken into account.

If you build the image and run it, you will notice that you always get an Invalid host header because of this.

This issue was introduced by commit 1d6c9cc985617930442f366724244412b66f45bc.

Thank you! I've built and tested this before, but I encountered some formatting and indentation issues on the new editor. While trying to fix them, I force-pushed this three times and didn't realize it was broken.

I will release a new image today.

Great! Thank you.
