[BUG] useSniffing parameter is actually dontUseSniffing

[kammerjaeger]

ECS integration/library project(s) (e.g. Elastic.CommonSchema.Serilog):
Elastic.Serilog.Sinks

ECS .NET assembly version (e.g. 1.4.2):
8.6.1

Description of the problem, including expected versus actual behavior:
The parameter is the opposite of what its name is, that is quite confusing.
See:

ecs-dotnet/src/Elastic.Serilog.Sinks/ElasticsearchSinkExtensions.cs

Line 81 in eac06c3

var transportConfig = useSniffing ? TransportHelper.Static(nodes) : TransportHelper.Sniffing(nodes);
