We'll need to adjust how we're defining the role that grew too large.

While we'll eventually need to split that GitHubActionsRoleNextstrainBatchJobs role into two (or otherwise tweak it) to accommodate the role trust policy length limit, in the meantime I've bumped that quota from 2,048 chars to 4,096 chars (the max that's automatically approved).

@j23414 Try again? Also, please merge this branch and push to main before planning and applying the changes.

Works, thank you! :D

Coming back here (after an "ah ha" moment in Slack) to note for posterity that this should have used WNV, as the actual repo name (e.g. https://github.com/nextstrain/WNV) and pathogen name (e.g. https://nextstrain.org/WNV and https://data.nextstrain.org/WNV_NA.json) are both capitalized. While GitHub's not case-sensitive when it comes to repo names, everything else involved is.
