502 Showing as ServerError vs BadGateway

[say25]

I was expecting the text for 502 to be BadGateway instead of ServerError not sure if this intended behavior or not.

Fix would be to extend this code with additional status codes:

Swashbuckle.AspNetCore/src/Swashbuckle.AspNetCore.SwaggerGen/SwaggerGenerator/SwaggerGenerator.cs

Line 691 in cbc1b7a

new KeyValuePair<string, string>("5\\d{2}", "Server Error"),
