[Tidy] Remove font assignment to elements in vizro-bootstrap

[huong-li-nguyen]

Description

• Update HF links to show app in full height/width view

• Removal of font-styling for elements p, label, ul, li, blockquote and a- based on this PR: https://github.com/McK-Private/vizro-bootstrap/pull/32

• These previously defined properties now lead to differences in the screenshots - decided to remove them and update all screenshots given that the QB design library doesn't assign any styling to elements either: https://github.com/mckinsey/vizro-qa/pull/122

  ```
  letter-spacing: -0.112px;
  line-height: 16px;
  ```
  

Result: Elements will have no font-styling attached and will inherit anything their parent has.

Would like a review mostly from @pruthvip15 and then another codeowner so we can merge 👍
