Vyper Compiler updates needed

[ryestew]

• Patrick error report:
  This contract won't compile:

# I'm a comment!

# SPDX-License-Identifier: MIT
# pragma version 0.4.0

my_favorite_number: uint256

gives this errror

this looks like the Vyper plugin is not parsing the error message correctly.

Also try with:

pragma version 0.4.0
For some reason, it only works with:
pragma version ^0.4.0

and

• Toaster needs updating - when you clone the vyper examples repo - it says in the toaster - snekmate
