docs: explain Jaeger and collector bundling in getting started guide

[Garvit-77]

Summary

According to the DoD(3 Definitions) the changes were made.
Made Changes in 2 Documents namely getting started and otel(guides)

The motivation was to provide a Clear Documentation and a better understand of the concept of collectors to the users of Keptn and Jaeger.

This addresses an issue raised on Slack (link), where inconsistencies were found between the "Getting Started" guide and the main Jaeger documentation about how the OpenTelemetry collector is used. The response by @agardnerIT clarified the confusion, and the changes ensure this information is reflected in the Keptn documentation.

Fixes #3538

I think this issue can be solved with much less documentation. Pls see my other comments. Sorry for the inconvenience here 😅

[mowies]

Please remove this whole section, it's not necessary to explain, how the OTel collector works. People can read good documentation about it in the OTel docs that are linked already.

[Garvit-77]

@mowies in the DoD it's mentioned to

1. Detailed explanation in the Otel guide page about how the otel collector wrks in case you do not want to use Jaeger allInOne.

[mowies]

That is not needed. People can read about how the collector works in the OTel docs. No need to document this on our side.

[mowies]

Instead of this note, please reorder the items above so that the OTel collector is right below Jaeger and then add in parentheses:

(in this guide, we will use the OTel collector that comes bundled with the Jaeger `allInOne` image)
