Fixes

• Partially fixes [Accessibility] Accessibility Issues Identified on the Website #815 by @ginabeki

Description

This PR addresses the following accessibility issues:

1. Ensured that all links contain meaningful text where necessary and added aria-labels for improved screen reader accessibility.
2. Cross-checked all image tags to confirm the presence of descriptive alt text, and updated or added alt text where appropriate for better understanding.
3. Verified that all forms adhere to the requirements outlined in the design system, improving accessibility and usability.
4. Added the document language attribute () to improve how screen readers interpret the content.

Technical details

A comprehensive accessibility audit of all files in the templates was conducted, to systematically identify and resolve issues. Addressing these concerns will improve the user experience, particularly for visitors with disabilities.

The PR was cloned and pulled to my local machine, where I carefully reviewed and resolved the identified problems.

Regarding the forms, no labels were added, as per the design system's requirements, which specify that the forms do not require labels.

@TimidRobot I really don’t think it’s partially fixed , I think it’s completely fixed because the other bullet point was to add label for forms
And the only forms i found was in the footer , which I cross checked with the requirement in the Design System.
And the Design system does not have labels added to the form .
