a11y: normalize TeamMember social link labels and mark icons aria-hid…

[mdimamhosen]

Description

Fixes #8552

On the Team page (/community/team), the social links for GitHub and Personal Site previously used generic accessible labels ("GitHub Profile" and "Personal Site"). On a page listing dozens of members, screen reader users navigating links or rotor menus encountered identical, ambiguous links without knowing whose profile was referenced (WCAG 2.4.4 Link Purpose in Context).

This PR:

• Normalizes GitHub links to use aria-label={${name} on GitHub}.
• Normalizes Personal site links to use aria-label={${name}'s Personal Site}.
• Adds aria-hidden="true" to decorative icons (IconTwitter, IconThreads, IconBsky, IconGitHub, IconLink) to ensure clean accessible names without conflicting nested SVG labels.

Verification

• yarn tsc passed (0 errors)
• yarn prettier:diff passed
• next lint passed

Details

Only the gzipped size is provided here based on an expert tip.

First Load is the size of the global bundle plus the bundle for the individual page. If a user were to show up to your website and land on a given page, the first load size represents the amount of javascript that user would need to download. If next/link is used, subsequent page loads would only need to download that page's bundle (the number in the "Size" column), since the global bundle has already been downloaded.

Any third party scripts you have added directly to your app using the <script> tag are not accounted for in this analysis

Next to the size is how much the size has increased or decreased compared with the base branch of this PR. If this percentage has increased by 10% or more, there will be a red status indicator applied, indicating that special attention should be given to this.
