KvKeyPart types lists symbol as valid, this is not supported

[kitsonk]

Version: Deno 1.41.0

The unstable types for Deno.KvKeyPart indicates that a symbol is a valid key part:

deno/cli/tsc/dts/lib.deno.unstable.d.ts

Lines 1318 to 1324 in 942b2aa

	export type KvKeyPart =
	| Uint8Array
	| string
	| number
	| bigint
	| boolean
	| symbol;

But using a symbol as a key part results in the following error:

Uncaught TypeError: expected string, number, bigint, ArrayBufferView, boolean
    at doAtomicWriteInPlace (ext:deno_kv/01_db.ts:624:16)
    at Kv.set (ext:deno_kv/01_db.ts:97:32)
    at <anonymous>:1:31

The bug is in the type - this should not be a valid type in the key.
