Add Autogrill and Chef Express to cafe.json

[Mannivu]

Both Autogrill and Chef Express have cafes and restaurants POIs, so I added them to both cafe and restaurant entries

Both Autogrill and Chef Express are catering companies operating a variety of external and internal brands in airports/train stations/motorway services. As far as I can tell, the only thing using the Chef Express brand is https://www.chefexpress.it/insegna/chef-express/, which I'd call a cafe. Autogrill operates a cafe using their branding, but calls it Acafè. They also have a cafeteria called Autogrill Più. I don't see anything on their website that uses just the Autogrill branding, other than the service areas themselves.

While I can agree on Chef Express, there are a lot of Autogrill POOs that are not restaurants and have the "Autogrill" insigna (I have to use GMaps since Autogrill hasn't got a dedicated page for their restaurants and cafes)

• Autogrill Santerno Est https://maps.app.goo.gl/F2ir7Xx1D89rsSTm7
• Autogrill Somaglia Est https://maps.app.goo.gl/BDLgLCWwBpj9CBZC8
• Autogrill Valle Aterno Ovest - Nuova Sidap srl https://maps.app.goo.gl/sQXKgayUuRgVHCeE6
• Autogrill Civita Sud https://maps.app.goo.gl/m7iuqRAn38BSsshi8

So having "Autogrill" for restaurants is not wrong IMHO.

@DnaX @ThorOnTheRocks (Listed for Italy on #2588), do you have thoughts on whether Autogrill belongs in amenity/restaurant.json?

I'm not particularly opposed, but I'm also not confident enough to merge it myself.

@AntiCompositeNumber sorry for the late answer.

For me Autogrill always have a cafe zone as well restaurant area. For suce you can eat decently there!

Altrough this PR cointains too much things in order to be merged.
