Subtype operator in parametric composite type definition not captured in Neovim

[mroavi]

The <: operator in the code below is not properly captured and highlighted in Neovim. I think this can also be solved with a query (in the future, should I open this kind of PRs in https://github.com/nvim-treesitter/nvim-treesitter instead?)

struct Point{T} <: Pointy{T}
  x::T
  y::T
end
