Update list of built-in actors (currently 11 there should be 16)

[eshon]

This page is out of date because it only lists 11 built-in actor types:

https://docs.filecoin.io/reference/built-in-actors

Might be easier to just link to the code:

https://github.com/filecoin-project/builtin-actors/tree/v14.0.0/actors

Please also mention that the following are singletons for the network:

https://github.com/filecoin-project/builtin-actors/blob/v14.0.0/runtime/src/builtin/singletons.rs#L19-L30

Also why does the following page talk about EVM actors with no mention/context of Filecoin's built-in actors?

https://docs.filecoin.io/smart-contracts/filecoin-evm-runtime/actor-types

(and vice versa, why does https://docs.filecoin.io/reference/built-in-actors not mention the EVM actors?)
