fix: Restore last corrupted heading emoji on SVM page

The 'Implementation using Libraries' H2 on the Support Vector Machines
page still rendered as '=" Implementation using Libraries' (the 🔢 emoji
had been mojibaked to two stray ASCII bytes). Restored the emoji so the
site is fully free of encoding corruption.
