Add Alignments to Open Badges 3.0 Display

[kayaelle]

Is your feature request related to a problem? Please describe.
Open Badges 3.0 may contain "alignments" to educational frameworks: https://www.imsglobal.org/spec/ob/v3p0#alignment

and we want to display them in the credential.

Describe the solution you'd like
The alignment object could be found in the achievement object. If found, we should display the header "Alignments" and below, list each alignment as:

<a href=""targetUrl">targetName</a>
targetDescription

Notes:

• targetDescription is optional
• even though it is required, targetURL may not be present, in those cases, just display the name in regular body text.
• Other elements like: targetCode, targetFramework, and targetType can be ignored

Example of an Open Badge with Alignments:
