[Feat] Add more customization within recipe-buddy

[adan-ea]

• We should be able to change the name of the recipe directly from this page here
  

• Most websites gives the recipe with the indications of how many people it serves. Would be great to scrap that info (or at least be able to let us update it at will)

• I don't know exactly how the steps are collected but could be nice to let us set some sort of template as to how we want the data. Instead of receiving one big paragraph with every steps
  Like :

## Step {{step.number}}
{{step.value}}

Besides that thanks a lot for the app. I finally found the motivation to add the recipes to my grocy thanks to your goblins :]
