Misc. fixes, which I'm snapshotting into a release so that I can follow up shortly with another release that depends on Compose v1.2.1, which was just released recently.

Frontend

• Refactor alignment modifiers
  • Introduce Kobweb's version of AlignItems, JustifyItems, etc. classes, since the Compose for Web versions don't handle baseline and overflow settings.
  • Add missing modifier for placeItems
• Rename kobweb.core.navigation.Link to kobweb.core.navigation.Anchor, to avoid confusion caused with Silk's own kobweb.silk.navigation.Link widget.
  • Technically, an Anchor is a more robust A tag, while a Link is a specific anchor that renders the underlined link text we all know and love when using the web.
  • In most cases, users will want to use Link and not Anchor.
• (Possible backwards incompatibility) Refactor the elementScope parameter in all Silk widgets, changing them into a version that takes a ref listener (with a callback that receives an ElementRefScope)
  • This makes it safer to get access to the underlying raw element for a widget without exposing an unnecessary composable block.
  • Before, to get a raw element that backs a widget:

    Widget(elementScope = { 
       DisposableSideEffect {
          // use scopeElement here
          onDispose {}
       })
    

    After:

    Widget(ref = ref { element -> ... })
    // or, if you need dispose handling:
    // Widget(ref = disposableRef { element -> ...; onDispose { ... }})
