vhs: äldre versioner att ladda ner

Freeze Frame ❄️ 📸
With VHS `v0.7.0`, you can capture the any moment during tape execution. Just add in `Screenshot <filename>.png` to your tapes:

```
Type ls
Enter

# Capture the output of 'ls'
Screenshot files.png

# Now, continue as you normally would
Type 'cd ..'
Enter
```

Your tape outputs a GIF, and outputs a file named `files.png`.

Copy-Paste Functionality!
VHS can now talk to your system clipboard. Please keep this in mind when executing tapes from unknown sources.

> [!WARNING]
> You should never `curl` pipe into VHS, it's similar to executing a bash script on your computer!

```
Copy "https://github.com/charmbracelet/huh"

Type 'curl '

Paste

Enter
```

New Modifiers + Keys Alert!
VHS `v0.7.0` has some new additions: introducing the top level `Shift+` modifier and the `Insert` + `Delete` keys!

```
# Shift things up a bit!
Shift+A
Shift+Tab
Shift+Enter

# Insert and delete to your hearts desire:
Insert
Delete
```
