External Link Icon Causes Redundant Link Announcements via Screen Reader

[racecn]

External link icons with role="img" and aria-label="External link" cause screen readers to announce "mitre external link link" - the icon's label gets concatenated with the link text, creating confusing redundancy.
The external link icon should not interfere with the link's accessible name.

2.4.4 Link Purpose
4.1.2 Name/Role/Value

Current Behavior:
NVDA announces: "mitre external link link"
Redundant and confusing for screen reader users

Expected Behavior:
Should announce: "mitre, external link" or just "mitre (opens in new window)"
Clear, non-redundant link purpose

Steps to Reproduce:

1. Navigate to any ER page with external links. such as:
   .../services/escape-room/our-story
2. Use screen reader to navigate to MITRE external link
3. Observe redundant "link" announcements

@rachaelbradley, would it be a good option to change the aria-label from "External link" to something like "- Opens in new tab"? That way, it would prevent the announcement of "link" twice.
