[BUG] [Aspnetcore2.1] Missing tag closure of StringLength attribute

Created by: seda-zor

Description

I have a parameter with min/max length attributes. When I run the generator, there is a missing tag closure of StringLength attribute.

public virtual async Task<List<Facility>> FacilitiesList([FromQuery][StringLength(3, MinimumLength=3)string area, [FromQuery]string addressCountry)

It can be seen in these resource files as well: https://github.com/OpenAPITools/openapi-generator/search?q=MinimumLength
