otelslog: WithSource

[Jesse0Michael]

Problem Statement

I would love to move to an otel logger from slog using the slog bridge, but there is one feature that I would miss.
The HandlerOptions used to configure a slog JSONHandler or TextHandler allow for a bool toggle AddSource which, when set, will include the source file information of where the log occurred in the log attributes.

Proposed Solution

I would like to add a bool source field to the otelslog config that is set in a new WithSource Option that takes a bool as a parameter. When source is set, the otelbridge would mimic the behavior of the slog options and include the source information of the log as attributes when converting the slog record.

This makes sense. Do you want to work on a PR?
Should we also provide ReplaceAttr? (in a different PR)

[Jesse0Michael]

Yeah, I can work on a WithSource PR!

ReplaceAttr isn't something that I personally use, so I am less familiar with it... but i imagine someone out there could want it.
