[Outreachy Task Submission] Do not display contact email address when empty.

[nimishmedatwal]

Problem with accordance to accessibility guidelines:

• The element lacks visible text that screen readers can interpret, thereby hindering accessibility for visually impaired users.
• It is included in the tab order but lacks accessible text, which means keyboard users may not understand its purpose or function.
• Empty tag, providing no meaningful content or interaction for users.

 <a _ngcontent-cll-c66="" class="company-info__email" href="mailto:" data-qa="contact-email"></a> 

Proposed solution

• Do not display `contact email address when it's empty.
  When empty
  
  When not empty
  

• Accessibility Attributes: Ensure that the tag has appropriate accessibility attributes to make it accessible to users of assistive technologies, such as screen readers. This includes adding aria-label or title attributes to provide additional context for the link.
