Support dynamic evaluation of description field in the RequestBody annotation

[kbos-work]

Is your feature request related to a problem? Please describe.

While using the @RequestBody annotation it doesn't replace variable content ${myapicall.request_body.description} for the description. Example the following will result in outputting the variable as is inside the swagger doc

@RequestBody(description = "${myapicall.request_body.description}")

Describe the solution you'd like

While using annotations in for example @Operation and @Parameter it supports dynamic evaluation of properties. For example the following will generate the swagger doc in which the summary/descriptions are replaced with the corresponding values from the property file

@Operation(summary = "${myapicall.summary}", description = "${myapicall.description}")
public ResponseEntity<Object> doApiCall(@Parameter(description = "${myapicall.params.example}", required = true) @RequestParam String example) {

}

It would be great if the same would be supported for @RequestBody. Looking deeper in the source it would effectively mean to support the usage of PropertyResolverUtils inside the RequestBodyService similar to GenericParameterService

Describe alternatives you've considered

• Only real alternative is defining it directly in code, but in case of an multi language setup that would not work

It would resolve also swagger-api/swagger-ui#9296
