Markdown doesn't render Slack deep links

[p-fernandez]

Slack allows direct actions to be executed through deep links when the Desktop / Mobile app is installed.
When trying to render a deep link inside any markdown file is not being processed properly.

Examples that are currently happening to me:

[![Slack](https://img.shields.io/badge/Slack-4A154B?style=for-the-badge&logo=slack&logoColor=white)](slack://user?team=TEAM_ID&id=USER_ID)

[`#channel-linked-name`](slack://channel?team=TEAM_ID&id=CHANNEL_ID)

Is this caused because the markdown flavour used by Github to render markdown?
