Remove IAM user here.hfla

[ale210]

Part of #205 (step 1 of 2: remove here.hfla; a follow-up PR recreates the account as here, the GitHub handle)

What changes did you make?

• Removed the iam_user_herehfla module block from terraform/aws-users.tf

Why did you make the changes (we will use this info to test)?

• The account is being recreated under the GitHub handle here, as the naming convention expects (the block still carried its # Replace with GitHub handle placeholder)
• Expected plan: 0 to add, 0 to change, 3 to destroy: the user, its login profile and its read-only-group membership
• The live user has no access keys, MFA devices or attached policies, and its password was never used, so force_destroy has nothing extra to remove
