Replace List log value kind with Slice

[MrAlias]

The specification states this type as ...

An array (a list) of any values

We currently use the term "List" for these value types in the logs bridge API design.

Given Go does not use this term, it seems fitting to call it something more native. Use Slice instead:

const (
	KindEmpty Kind = iota
	// ..
	KindSlice
	// ...
)

// Value factory:

func SliceValue(vs ...Value) Value

// Value accessor:

func (v Value) AsSlice() []Value

// KeyValue factory:

func Slice(key string, args ...Value) KeyValue

Alternatives

• We could also use the term "Array"
• Leave it as "List"

I support the proposal. For what I remember the only reasons I decided to call it List were:

• the term exists is spec and I thought it might be easier by TC when reviewing
• the name is shorter (by 1 character 😆) than Slice

I find Slice more accurate and idiomatic

Plan is to wait for #4907 to merge prior to addressing.

I also support the proposal, as we already use the slice term in our kv.go. Using slice can keep consistency.
