Allow markdown (for example links) in title of a card

Is your feature request related to a problem? Please describe.
Since there is currently no interface with tasks or possibility to sync task we often use the Nextcloud task app in combination with DAV sync to Android to manage subtasks seperately related to a overal task/action in the board. So instead of creating subtask in a card we create a task in the nextcloud task app including the subtasks. This makes it easier to track tasks on the fly, to complete them or to add them. To easier navigate from a deck card to this task we currently create a link to that task in the description of a card. But it would be great if we could navigate to this task (link) without opening the card.

Describe the solution you'd like
If the title of a card renders markdown I could create a link with [Link](Url) in the title and click on it without opening the card. But markdown is not enabled for titles. So enabling markdown creates some benefits.

Start by locating where Deck card titles are rendered in the JavaScript frontend and compare that with the existing markdown rendering used in card descriptions. Verify how a markdown link in a title should behave without opening the card, then confirm the rendered title and navigation behavior manually or through the relevant existing tests, if present.
