MANDATORY - Updated workflows

[Mara-Li]

Hello!
I updated the workflows to auto_update and the workflows that clean unused medias and update the requirements. You need the 0.0.4 version!

You must do :

• Create a .env file in .github folder.
• With the following value. You need to edit the the WORKFLOW_TYPE to corresponding to your methods (netlify or gh-pages') :

WORKFLOW_TYPE='netlify' or 'gh-pages' (or leave blank : '')
CLEAN=true
IMG_DIR='assets/img'
AUTO_MERGE=false

• Create the GH_TOKEN secrets.
• Register it as a secrets. As I said, the secret must be named GH_TOKEN.

Obviously, you can change any option, I present here only the default.
