[ENG-987] Handle non-existent security requirement in “konfig fix”

[dphuang2]

basically, if an operation is referring to a non-existent security requirement we should just auto map it to an existing security requirement with the lowest edit distance as the non-existent security requirement was most likely a typo

we should make this a lint rule too
