[TypeDefs] Deno.core.heapStats() Function Does Not Exist

[zicklag]

deno/core/lib.deno_core.d.ts

Lines 71 to 72 in 7219930

	/** Get heap stats for current isolate/worker */
	function heapStats(): Record<string, number>;

I might be missing something, but it appears that the heapStats() function documented here doesn't exist. I've attempted to run the function in a script with deno_core, but it wasn't found. Also, I can't seem to find an implementation of the operation in the Deno source.

It was removed, but the type definitions not updated, but should be removed from the definitions.
