Fixes

Fixes #544 by @saurabhkamane

Description

• Converted button-like links into real <a> tags to improve accessibility and standardize link behavior.
• Ensured all links open in a new tab using target="_blank" with rel="noopener noreferrer".

Technical details

• Updated clickHandler to prevent default behavior.
• Used Vue's $nextTick to properly modify modal links after the DOM updates.

Tests

1. Run the project locally.
2. Go to the Help section.
3. Click on each link and confirm they open in a new tab.
