fix: prevent double quotes in pull quotes

[tanujbhaud]

Done

• Added quotes: none to the .p-pull-quote mixin to prevent browser default quotes from appearing when the pattern is applied to a <blockquote> element.
• Explicitly reset ::before and ::after content on the pull quote container to none to avoid overlapping pseudo-elements in environments with global blockquote styles.

Fixes #5711

QA

• Open Pull quote variants example
• To simulate the bug in the browser console/dev tools, apply the following styles to any pull quote blockquote element:

  blockquote { quotes: "“" "”"; }
  blockquote::before { content: open-quote; color: red; }

• Verify that with the fix, the red quotes do not appear.
