Parsing error with leading & in a type

[iamawatermelo]

local f: & number & string = "hi"

This is valid Luau code:

StyLua cannot format it, though:

sarah@localhost ~/project (main) [2]> StyLua example.luau
error: could not format file example.luau: error parsing: error occurred while creating ast: unexpected token `&`. (starting from line 1, character 10 and ending on line 1, character 11)
additional information: expected type after colon
sarah@localhost ~/project (main) [2]> StyLua --version
stylua 0.20.0
sarah@localhost ~/project (main)>

StyLua was installed from aftman.

Requires support upstream in full-moon, our Luau parser
