Fixes #5259

Hey @AndreasHae. Looks good, but you need to run npm run build before pushing any code, this command will build your project and also notify if there is any error. In your case after adding data/presets/presets/leisure/bandstand.json if you run npm run build it will update the following four files :
data/presets.yaml
data/presets/presets.json
data/taginfo.json
dist/locales/en.json

I would suggest you to build the code and push the changes again.
Thanks!!

Thanks @AndreasHae - I'm going to merge and change the building tag from the "tags" to its own field.

Talking about this part:

    "tags": {
        "leisure": "bandstand",
        "building": "roof"
    },

Everything in the tag list is required in order for the preset to be matched. This means that the way the preset is currently set up, if a bandstand didn't have exactly building=roof it would not be recognized as a bandstand. So I'm going to put the building tag into a field instead, just in case people tagged it as building=yes,building=gazebo,building=shelter,building=bandstand or some other thing.

The tag building is not is not needed here.
