fix: links to subtitles with special characters (#1949)

This issue is related to #1006 . The $vuetify.goTo() function expects a UTF-8 ev.target.hash . However, the markdown CRM URIencodes the ev.target.hash (this is great for browser compatibility, not so much for Vuetify)

Adding decodeURIComponent() to ev.target.hash fixes compatibility with Vuetify.

This fixes GitHub issue #1873
