The URL for homepage should link to package inside monorepo

[trivikr]

Is your feature request related to a problem? Please describe

The homepage field for the individual packages (if present) links to root of the monorepo.
The folks using the link and landing on GitHub have to go through monorepo structure, and find out the correct package.

For example, open @opentelemetry/instrumentation-aws-sdk on npm, and click on Homepage in the right sidebar.

Screenshot

The page opened will be https://github.com/open-telemetry/opentelemetry-js-contrib#readme

Describe the solution you'd like to see

The homepage config should link to folder where source code for the package is present.

For @opentelemetry/instrumentation-aws-sdk package, the URL stored in homepage should be https://github.com/open-telemetry/opentelemetry-js-contrib/tree/main/plugins/node/opentelemetry-instrumentation-aws-sdk
