[Docs] incorrect description for Term Selection Parameters (max_doc_freq)

[dharada]

Describe the feature: this is not feature request. Docs bug.

Elasticsearch version (bin/elasticsearch --version): any

Description of the problem including expected versus actual behavior:

Current document says that

max_doc_freq | The maximum document frequency above which the terms will be ignored from the input document. This could be useful in order to ignore highly frequent words such as stop words. Defaults to unbounded (0).

but actual default is Integer.MAX_VALUE (not 0)
