[FR] Updated/Additional textobject captures

[bashful-strix]

This may be a neovim-specific thing, but the textobject captures provided don't line up the expected ones; I've got these overrides locally which seem to do the trick:

(comment) @comment.inner

[
  (data)
  (type)
  (newtype)
] @class.inner @class.outer

((signature)?
 (function
   rhs: (_) @function.inner)) @function.outer 

(exp_lambda) @function.outer

(data
  (type_variable) @parameter.inner @parameter.outer)

(patterns
  (_) @parameter.inner @parameter.outer)

Happy to raise a PR to either replace or add these in addition if desired. Thanks!
