Pull Request Overview

This PR updates the instrumentation links in the monitor-opentelemetry README to reflect the new package structure in the OpenTelemetry JS Contrib repository.

• Swapped old plugins/node URLs to the new packages/instrumentation-* paths for supported libraries.
• Updated the “Other OpenTelemetry Instrumentations” link to point to the new packages directory.
• Ensured consistency across Distributed Tracing and Logs sections.

• The new instrumentation links under Distributed Tracing are no longer nested under the HTTP/HTTPS bullet—consider adding two spaces of indentation before each - [MongoDB], - [MySQL], etc., to maintain a proper nested list structure.

- [MongoDB](https://github.com/open-telemetry/opentelemetry-js-contrib/tree/main/packages/instrumentation-mongodb)

sdk/monitor/monitor-opentelemetry/README.md:217

• In the Logs section, the Bunyan and Winston entries appear unindented compared to the previous nested list style—add consistent indentation (e.g., two spaces) to indicate these are list items under the Logs heading.

- [Bunyan](https://github.com/open-telemetry/opentelemetry-js-contrib/tree/main/packages/instrumentation-bunyan)

sdk/monitor/monitor-opentelemetry/README.md:221

• This line was dedented and no longer appears as a list or paragraph under Logs—consider restoring a blank line above and formatting it as either an indented paragraph or bullet to keep it visually grouped with the Logs items.

Other OpenTelemetry Instrumentations are available [here](https://github.com/open-telemetry/opentelemetry-js-contrib/tree/main/packages) and could be added using TracerProvider in AzureMonitorOpenTelemetryClient.
