LSP: autocompletion types in import statement should account for already-typed type keyword

[quentin-fox]

On Gleam 1.2:

When autocompleting an unqualified type import, the LSP always inserts the type prefix before.

e.g. when triggering autocomplete for Dict from here:

import gleam/dict.{type D }
                         ^

We end up with

import gleam/dict.{type type Dict}

Another related bug:

If type is already typed in the import statement, it should ideally only allow autocompletion of available types, instead of all exported symbols.

e.g.

import gleam/dict.{type }
                       ^

The get function is one of the suggestions, when the LSP should know (? unless that's not desired behaviour) that I'm only looking to import types.
