Update for Fastify v5

[synapse]

Ref: fastify/fastify#5116

⚠️ There is one small issue with this one, and it's the NextJS dependency. Upgrading it to v14.x will ignore the basePath option. Even thought the basePath is still present in their config docs and typings it does not work. I am unsure if this doc saying that it was removed might have something to do with this issue.
I am open to discuss what would be the best way to fix this one.

I think we need to drop node 14 and 16 for this one

it was always part of the original plan, wasn't it? fastify/fastify#5116

Most likely this will simply mean updating dependencies, dropping Node <= 16, and updating CI configuration accordingly

Hey, can you pull form main? I can't realistically resolve the package-lock conflicts on the web interface...

And if you could also add node 22 to the test matrix it would be great

Then this is good to go!

@mcollina @gurgunday can we have this release? this package has not yet been released for fastify v5...
