REST-connector-example (lb3) shows up under lb4 docs

Describe the bug

I was looking up an example of the REST connector and reached here. Though the example shows up under lb4 docs, the example is actually for lb3.

Is this somehow expected?

Although it's related to the documentation repo instead of framework.

You can check this (unofficial) example of rest connector in lb4: https://github.com/shubhamp-sf/lb4-rest-connector
