Lift to SpeziSpeech 1.0, NavigationBar item improvements (#7)

# Lift to SpeziSpeech 1.0, NavigationBar item improvements

## ♻️ Current situation & Problem
`SpeziChat` is still dependent on an old tagged version of
`SpeziSpeech`.
In addition, the navigation bar share icon always allocates space (even
when the icon is not shown - initially done for animation purposes),
leading to issues with `View`s reusing the `ChatView` while adding
navigation bar items.


## ⚙️ Release Notes 
- Lift `SpeziChat` to tagged 1.0.0 version of `SpeziSpeech`.
- Adjust navigation bar item behaviour of export button
