feat: Knowledge Panel details page accessibility improvements

[g123k]

Hi everyone,

Here are my accessibility changes:

• The title is now "Details for XXX with YYY" (XXX is the name of the section and YYY the product name)
• Positive and negative points are not merged in the full-page
• The Nutri-Score card is not considered as a button within the page

Unfortunately, I can't fix "-> Button" (cf #5289), because it's some HTML provided by the server.
