fix: Making alt text less redundant

[CBID2]

• What kind of change does this PR introduce? (Bug fix, feature, docs update, ...)
  There was repetitive alt text for the icons/links on the website. So I gave them more descriptive names.
• Why was this change needed? (You can also link to an open issue here)
  According to Deque University, repetitive alt text can confuse screen readers, thus, making it difficult for users with disabilities to navigate this project's website.
