Set simulacrum version to 0.11.0

[ghost]

This is required to compile cats for scala 2.13.0-M1.

see https://gitter.im/typelevel/cats-dev?at=59a03515a7b406262dc7722b

See also https://gitter.im/scala/community-builds?at=59a2c72eba0f0f6e38ea700c and links from there as well.

tldr is we wanted to check with scala team if these are known issues on 2.13.0-M1 as well.

This PR will override #1863, so sorry to @shokohara but thanks too!!
