Copy and Run command on homepage

[jromero]

Summary

Use Case 1: New User

As a new user, looking for the easiest way to understand the value of Cloud Native Buildpacks, I'd like a simple command I can run against my application source on the homepage of buildpacks.io.

Use Case 2: Returning User

As a returning user, I'd like to be able to go to buildpacks.io and copy a snippet to run against my application source.

Proposal

Add a (copy and pastable) snippet between the hero and secondary content which a user can select a builder (based on their language of choice).

NOTE: Individuals contributing this should propose a design and get consensus on it before creating a PR.

Considerations

• Without Create a page to list of suggest builders #111 or Add builders information to buildpacks page registry-api#56 we'll need to maintain some static data on our end for the suggested builders.

Some considerations around implementing something like this is making sure that the user has pre-requisites already installed on their machine. We could probably use the auto-detection page from pack install and add a builder dropdown for the user to select one and generate the getting started instructions. We should also move this somewhere front and center. Possibly the home page? cc: @importhuman who had some questions and ideas.

• Configure default builder in installation so new users don't have to worry about it
• A couple of images showing pack in action, along with the installation and usage steps
