Disable ESLint rule for @octokit/core

We shouldn't have to do this:

Using github.getOctokit from @actions/github directly instead of using
its dependency, @octokit/core, would be preferable here.

But it turns out getOctokit cannot be used with the paginateGraphql
plugin, despite actions/toolkit#1181
(I couldn't get it to work).
