[JavaJaxRS] Fix parameter annotation generation

[michaeldavis-wf]

When generating parameter annotations with the JavaJaxRS generator, those annotations are invalid and cause compilation errors. Currently, any non-cookie parameter is generated as such:

public Response listUsers(@Parameter(ParameterIn.HEADER, description = "Http Authorization Header" ,required=true) @HeaderParam("Authorization"))

Which throws a compilation error:

annotation values must be of the form 'name=value'

This appears to be a bug introduced recently.

This now generates as such, which compiles correctly:

public Response listUsers(@Parameter(in = ParameterIn.HEADER, description = "Http Authorization Header" ,required=true) @HeaderParam("Authorization"))
