Show share options even if navigator.share is disabled

[ebroda]

In Firefox navigator.share is disabled by default and therefore the share icon isn't shown.
https://developer.mozilla.org/en-US/docs/Web/API/Navigator/share#browser_compatibility

Scheinbar nutzt ihr für das die share()-Methode genutzt, die ist in Firefox aber per Default deaktiviert.
Nur wenn man “dom.webshare.enabled preference (needs to be set to true)” in about:config setzt, wird das korrekt befüllt und angezeigt.
Hier wäre also nochmal n Fallback für Firefox bzw. wenn die Methode nicht verfügbar ist, zu prüfen, dass es sonst einfach in die Zwischenablage kopiert wird.

The corresponding file has an explicit check for navigator.share:

vca-ui/src/elements/VcaShareIcon.vue

Line 28 in d3619ff

if (navigator.share) {

A possibility would be to add an els branch and remove isShareMobile.

} else {
navigator.clipboard.writeText(this.text)
}

But the user should also get a hint, that something has happened. Best would probably to trigger as message box like in other cases (e.g. on save) - but I'm not sure if that's possible to be triggered from here as the Notifications are in pool-webapp?

If you want, you can try to build it :-)
If you need further feedback for the notification trigger pleas give the card the redefine label and assigne it to Tobi, but it can take a while because the MTG has priority right now.
