Disimbiguate similarly named implementations

[adamvoss]

I noticed while preparing #123 that there are numerous similarly named libraries listed on the Software page. For example Java has two implementations called "json-schema-validator"

I propose that when repositories have the same name, the user/org should be included to qualify which implementation is being referenced. For example Java would become:

• Java
  • java-json-tools/json-schema-validator
  • everit-org/json-schema
  • networknt/json-schema-validator
