chore: Drop Use IAM roles guide, replaced by inline recommendations

[bebosudo]

In the process of removing mentions of the nf-tower-aws repo, I found this docs page not linked to from any v25.x page anymore, and already removed from cloud docs: the content in the page is already being provided in a section of the AWS Batch guide.

Pull request overview

This PR removes the "Use AWS IAM roles" guide from documentation versions 25.1, 25.2, 25.3, and current, as the content has been replaced by inline recommendations in the AWS Batch compute environment guide. The guide references external resources from the deprecated nf-tower-aws repository and is no longer linked from v25.x documentation pages.

Changes:

• Removed use-iam-role.md files from versions 25.1, 25.2, 25.3, and current documentation
• Removed sidebar references to the use-iam-role guide from the same versions
