### Create hierarchical tags with colon delimiter in MapGet

Source: https://github.com/wilder-minds/swaggeruihierarchysupport/blob/main/readme.md

Example endpoint using a colon-delimited tag to create a hierarchy: 'Weather' as top level and 'Forcast' as sub-tag.

```csharp
app.MapGet("/weatherforecast", () =>
{
  var forecast = Enumerable.Range(1, 5).Select(index =>
      new WeatherForecast
      (
          DateOnly.FromDateTime(DateTime.Now.AddDays(index)),
          Random.Shared.Next(-20, 55),
          summaries[Random.Shared.Next(summaries.Length)]
      ))
      .ToArray();
  return forecast;
})
.WithName("GetWeatherForecast")
.WithTags("Weather:Forcast") // Weather is the top level, and the Forcast is the sub-tag
.WithOpenApi();
```
