Change new attribute syntax highlighting color

[cart]

I think #4474 is a good change, but im not a huge fan of coloring attributes as functions. I liked that attributes were "distinct" from function calls. My brain now mentally groups attributes and their functions as "the same":

I personally think the old coloring was much clearer.

Ideally it would use a different color that still visually groups with the concept of "attribute". Maybe a slightly lighter or darker version of the attribute color?

We can't control the color, but we can and probably should produce a dedicated semantic highlighting tag for attribute attr key.

You an customize the color yourself:

"editor.semanticTokenColorCustomizations": {
        "[Default Dark+]": {
            "enabled": true,
            "rules": {
                "function.attribute": "#9b9809",
            },
        }
    },

I believe we can close this, for #[inline] the inline is tagged as function.attribute and the #[ and ] parts are tagged as attribute.attribute which should give appropriate coloring options.
