New keywords:
- Set Viewport Size and Get Viewport Size
- `Switch Browser`, `Switch Context`, renamed `Switch Active Page` to `Switch Page`
- `Get Browser Catalog` to list all open browsers, contexts and pages
- `Close All Browsers`
Improvements:
- `Create Browser` and `Create Context` have options in type signature and parse them correctly
- We're looking into hiding optional parameters from LSP autocompletion but it might take some time
- Better activation of new browsers / contexts pages when using `Switch Browser` / `Switch Context`
- More stable Browser aliases when closing Browsers
