Remove lookup-refs (#286)

**Blocked by release -
#285

Part of insightsengineering/coredev-tasks#609

From now on, we will provide development dependencies in 
```
Remotes: repo/project@branch
```
format, so it's explicitly visible in the DESCRIPTION file and can be
handled by `pak::install`, `renv::install` and `remotes::install`.

With development dependencies specified in CJ Pipelines configuration,
this connection was hidden, and it was hard to install the package from
the main branch (or any other branch) locally from user's machine.
