"examples" field does not comply with OpenAPI 3.0 Specification

[ckho-wkcda]

According to OpenAPI 3.0 Specification,
the field "examples" should be a map.

Example:

examples: 
  foo:
    summary: A foo example
    value: {"foo": "bar"}
  bar:
    summary: A bar example
    value: {"bar": "baz"}

However, in the current implementation of this plugin, it is implemented as an array.

In serverless-openapi/src/DefinitionGenerator.ts

if (parameter.example) {
  parameterConfig.example = parameter.example;
// BELOW (Line 227)
} else if (parameter.examples && Array.isArray(parameter.examples)) {
// ABOVE (Line 227)
  parameterConfig.examples = parameter.examples;
}

private attachExamples(target, config) {
// BELOW (Line 307)
  if (target.examples && Array.isArray(target.examples)) {
// ABOVE (Line 307)
    _.merge(config, { examples: _.cloneDeep(target.examples) });
  } else if (target.example) {
    _.merge(config, { example: _.cloneDeep(target.example) });
  }
}
