path option in otel and http sources is not documented

[rdicroce]

The path option was added long ago to the http and otel sources (#2277 and #2297), but it is not documented on the OpenSearch website. See e.g. https://opensearch.org/docs/latest/data-prepper/pipelines/configuration/sources/http/. This option should be documented so people know it exists. The only reason I found it was because I stumbled into #3670 while trying to figure out how to get the OTel collector's otlphttp exporter to work.

@rdicroce , Thank you for catching this! Would you be interested in contributing the change to the documentation-website project with the documentation?

I can do that but I don't know what the default values are. That was my original problem that led me to discover the path option.

@dlvenable I can update the documentation-website. Can you please assign this issue to me. I will open a PR shortly.
