PR Summary

• Added data-nosnippet attribute to Dropdown Component
  The dropdown menu component in the code file switch.blade.php now includes a data-nosnippet="true" attribute. This improvement helps to avoid content within the dropdown getting included in search engine snippets, leading to more relevant search engine previews.

• Ensured Proper File Ending with Newline
  A missing newline character at the end of the code file has been rectified. While this might sound minor, ending a file with a newline is a common standard that ensures better compatibility across different tools and platforms.
