Which problem is this PR solving?

It's currently not possible to bundle @opentelemetry/instrumentation with many bundlers.

Webpack fails because it errors with Critical dependency: The request of a dependency is an expression. This is because webpack can see the require but can't reason about what is being loaded.

Rollup can only bundle the code if you include a plugin that can load json files.

Since auto instrumentation will not work when the code is bundled, why would this change even matter?

Sentry is using @opentelemetry/instrumentation as a dependency in their Node SDK. Some users will not care about instrumentation but will want to bundle their code and using require like this to load json files makes it impossible to use some bundlers or at a minimum requires extra bundler config to work around it.

Short description of the changes

Use readFileSync + JSON.parse instead.
