Create pwa_webpush submodule to manage push notifications

As in #51 this was merged into 2.x - should this issue be closed @AlexBorsody?

Just chiming in to say that webkit is joining the 2010s, adding Web Push as of iOS 16.4

As seems to be the norm for Apple nowadays, they seem to grudgingly implement these things because everyone else has, not because they want to. I've spoken to some of the old guard engineers at Apple, and let me tell you, some of them are truly painful due to how much disdain they have towards the web platform. I was literally told that they couldn't stand the fact that some websites have bad UX so they wanted to enforce their UI on everyone, but the web wouldn't let them, which sounds a lot like something they should talk to a therapist about rather than putting it on their millions of users. I'm not saying that to make light of mental illness, by the way - I've seen multiple therapists over the years.

I'm my "Why the web?" essay/manifesto, I conclude with this excellent quote by Mathias Schäfer that sums it up:

There are several relevant browsers in numerous versions running on different operating systems on devices with different hardware abilities, internet connectivity, etc. The fact that the web client is not under their control maddens developers from other domains. They see the web as the most hostile software runtime environment. They understand the diversity of web clients as a weakness.

Proponents of the web counter that this heterogeneity and inconsistency is in fact a strength of the web. The web is open, it is everywhere, it has a low access threshold. The web is adaptive and keeps on absorbing new technologies and fields of applications. No other software environment so far has demonstrated this degree of flexibility.

@Anybody it was removed a few days later https://git.drupalcode.org/project/pwa/-/commit/6f8359399b41bc78cd83ae42...

Nothing regarding web push notifications has been commited on 2.x since then.

Changing to active. It's more than "needs work", there's nothing ATM.

As of #60 this needs a new MR against 2.x-dev

Someone should please create a MR based on the work and discussions above for review. I'd still like to add this as submodule, but don't have the time to do it myself.

This would be a killer feature!
Please consider ECA instead of Rules integration.

Not sure if entirely relevant to this issue, apologies in case... I've built a module which implements Web Push library for PHP, DANSE and Push framework, tailored and tested - a single case scenario though - to work with PWA. Here: https://www.drupal.org/project/pf_notifications →
