Update dev server IAM policy…

… with changes made by James on the AWS Console.

I copied the policy¹ as JSON from AWS Console and pasted directly into
the file. After reordering to match the existing file contents, which
are sorted to be more readable rather than alphabetical, I confirmed
that this updated version of the file results in no unexpected changes
with `terraform plan` (after accounting for policy changes in other
PRs).
