Update index.md

Numbering of authorization methods did not work. All appeared with 1. ... instead of 1., 2., 3. (probably because of inserted pictures, who knows)

 ## Theming
 To configure theming in your data app, you can select from predefined themes or create a custom theme. Predefined themes include `Keboola`, `Light Red`, `Light Purple`, `Light Blue`, `Dark Green`, `Dark Amber`, and `Dark Orange`. Each theme has a specified primary color, background color, secondary background color, text color, and font. Users choosing `Custom` can manually set these values.
