It looks like `investigate` grants access to the whole `Special:Investigate` toolset,==== Goal
We introduced an `investigate` right to allow selective access for `Special:Investigate` page when we were in the development and testing phase for the project.
Now that we are in the deployment phase of the project, we no longer need to keep access rights for `Special:Investigate` and `Special:CheckUser` separate. includedWe should deprecate/remove the `Special:InvestigateLinvestigate` right and defer to `checkuser` and `checkuser-log` pagerights.
In order to let members of some global groups (namely staff, ombudsmen and stewards) to see the logs without actually using the tool, please split from `investigate` the ability to check the `Special:InvestigateLog` page by creating a new `investigate-log` right.
This already happens in the old CheckUser where we have `checkuser` and `checkuser-log`.
Thank you.==== Acceptance criteria
* Once `Special:Investigate` is deployed on a wiki all users with `checkuser` right should be able to access `Special:Investigate` and all users with `checkuser-log` right should be able to access `Special:InvestigateLog`.
* The `investigate` right is removed from the code and the config.
