feat: add PDF export functionality

[vikas-viki]

Description (Issue #1314)

I've added a new action (Export as PDF) to the toolbar. Clicking this option will open the print dialog, allowing users to save the article as a PDF. All the contents(texts, links, images, tables...) in the article are made available as it is.

(A demo video will be added below for better clarity.)

Changes Made:

• Updated language files with the new toolbar text (translations generated using Google Translate).
• No new packages were added. Instead, I used the native window.print(), which prints only the article, as all other components have data-hide-print.
• Added an icon for the new menu option along with the necessary code changes.
