Upgrade to Vert.x 5

[tsegismont]

It's not possible to upgrade this how-to to Vert.x 5 yet: there are no Mutiny bindings available for this version.

@jponge any idea about when Mutiny bindings for 5 will be published? After GA? Or are you working on a CR?

Q1 2025 would be a good target, but the generator needs work, it's not ready to support Future-only APIs at this stage.
