feat: Clarify the duplicate logging workaround

[vordimous]

Which problem is this PR solving?

• I spent a few days trying to figure out how to stop duplicate logs from happening while needing to use the OpenTelemetryTransportV3 to format my payload correctly.

Short description of the changes

• This adds some clarity and an example how to correctly disable the default logger in the auto instrumentation.

@vordimous How about this wording:

Suggested change

	> Logs will be duplicated if `@opentelemetry/winston-transport` is added as a transport in `winston` and `@opentelemetry/instrumentation-winston` is configured with `disableLogSending: false`. You must import `winston` after you have called `registerInstrumentations`.
	> ```js
	>const { WinstonInstrumentation } = require('@opentelemetry/instrumentation-winston');
	>const { registerInstrumentations } = require('@opentelemetry/instrumentation');
	>registerInstrumentations({
	> instrumentations: [
	> new WinstonInstrumentation({
	> // Disable the duplicate logging from the auto instrumentation
	> disableLogSending: true
	> }),
	> ],
	>});
	>// Winston import must be after the WinstonInstrumentation creation
	>const { OpenTelemetryTransportV3 } = require('@opentelemetry/winston-transport');
	>const winston = require('winston');
	> ```
	> Logs will be **duplicated** if `OpenTelemetryTransportV3` is explicitly added as a Winston logger transport **and** `@opentelemetry/instrumentation-winston` is active with the [Log sending](#log-sending) feature (the default). If you are both using `OpenTelemetryTransportV3` and instrumentation-winston, be sure to either disable instrumentation-winston completely, or disable its Log sending feature (`disableLogSending: false`). For examle:
	>
	> ```js
	> const { WinstonInstrumentation } = require('@opentelemetry/instrumentation-winston');
	> const { registerInstrumentations } = require('@opentelemetry/instrumentation');
	> registerInstrumentations({
	> instrumentations: [
	> new WinstonInstrumentation({
	> disableLogSending: true
	> }),
	> ],
	> });
	> const { OpenTelemetryTransportV3 } = require('@opentelemetry/winston-transport');
	> // Winston import must be after the WinstonInstrumentation creation
	> const winston = require('winston');
	>
	> // ...
	> const logger = winston.createLogger(...);
	> ```
