Prevent loading plugins for incorrect module

[dyladan]

In #621, the following code sample is given as an example

  plugins: {
    mongodb: {
      enabled: true,
      path: '@opentelemetry/plugin-mongodb-core',
    },
  },

Because the version matched, the plugin was loaded. PluginLoader should also check that the component name matches and emit an error log if the incorrect module name is detected. Instrumenting a plugin with the wrong library would be very dangerous.
