Document process for updating request for legal considerations page

[dorothyyeager]

Summary

What we're after:
As a user who is doing legal research on other compliance actions similar to mine, I would want to review any relevant requests for legal consideration.

We occasionally have to update the Requests for legal consideration page when there is a new LRA to add. The requests to update the page come from RAD and Audit. This happens very infrequently, so we need documentation to remember how to do it.
