[FR] Git block

[witc-git]

Description

A code block that pulls (and pushes if possible) its content from a Github file.

Impact

Code blocks linked to Git files can be very useful when using AppFlowy pages as documentation for something that has configurations in GitHub. This way the content of the 'guide's' code block is synced with the live code on GitHub for easy copy pasting when using the self created guide.
Use-cases can be software dev and homelab or other system setups that use Git and have private written documentation.
