Improve sidebar title for awesome-azd

[hemarina]

The current sidebar title on getting started in awesome-azd is not short and descriptive enough. Update the title for better branding.

We should use "Azd - from code to cloud in minutes" or some iteration of our tag line. Most of the sites we are modeling off of use the formula [product] + [ - ] + [tagline from landing page]
