Added Examples For Search & On_Search APIs For Languages

[joffinjoy]

Adding search and on_search examples for languages.

Based on these examples, we should be able to search for sessions using languages, and catalog should mention in which all languages each course or session is available in.

Schema is correct. But examples need minor corrections

tags : [
   {
       code: lang
       name: Language
       list: [
            {
               code: ENG
               name: English
            },
            {
               code: HIN
               name: Hindi
            }
        ]
    }
]

@ravi-prakash-v I have made this modification.

Hi @ravi-prakash-v , shouldn't Hindi and English be values? rather than keeping them as code.
