Test options for on demand editor

[djay]

fly.io has auto stop and start services and pay by hour. also has free tier.
so site you don't edit often and doesn't have search, you can use SSG + on demand editor to pay almost nothing

• small site so postgres DB is small. maybe versioning off?
• zodb disk cache so startup is faster? or try using Nick instead?

It's mostly working but the bug plone/volto#6283 is preventing hydra.pretagov.com/++api++ requests from working.

It's actually not recommended to use this proxy anyway, so instead we can setup hydra-api.pretagov.com instead and change the frontends to use this url instead.

We will then likely face the issue that the urls will be wrong also due to this bug plone/volto#6272
