Theme annotation token

[HadyMash]

Is your feature request related to a problem? Please describe.
There was previously an issue with the Preview LSP option where the UI Guides wouldn't work. When that was fixed, I turned it back on and noticed the syntax highlighting was different. I opened #3155 and I was able to change the colour of the variables. However, the @ and override have different colours and it doesn't match. Prior to turning on Preview LSP, using the One Dark Pro theme the @override would be pink. I do not care about what colour it is so long as they have the same colour.

Describe the solution you'd like
As advised by @DanTup in the previous issue, I would like to have a token for annotations so the @ colour can be customised.

Additional context
Issue #3155

I've changed annotations to by default be coloured the same as variables:

This won't match perfectly if you use a constructor directly (@ClassFoo()) as classes are coloured slightly differently, but I think in most cases annotations are fields/getters.

You can also override the colour of the @ using the annotation token in your settings like:

"editor.semanticTokenColorCustomizations": {
	"rules": {
		"annotation": "#00ff00",
	},
},

Thank you very much for your help @DanTup!
