Create ADOPTERS.md file to Encourage Adoption

[benjagm]

I would like to suggest the creation of an ADOPTERS.md file in the .github repository. The purpose of this file is to encourage organizations that have adopted JSON Schema to add their name and point of contact to the file. This will help grow the ecosystem around JSON Schema and build trust among potential adopters.

A good example of the ADOPTERS.md file can be found in the Microcks project's repository at Microcks ADOPTERS.md. It serves as a centralized place where organizations can showcase their adoption of the project.

Benefits of creating an ADOPTERS.md file:

• Demonstrates the real-world usage of JSON Schema.
• Provides visibility to organizations that have successfully adopted JSON Schema.
• Encourages other organizations to adopt JSON Schema.
• Builds trust in the JSON Schema ecosystem.

Let's create an ADOPTERS.md file. It will greatly benefit JSON Schema's Ecosystem. Thank you!
