Relationship migrations confuse pk and primary_key

[mcvmcv]

Hello, I think this will be a quick fix.

Describe the bug
Running SearchLight.Migrations.create_relationship_migration creates a file named
2022..._create_relationship_table_model1s_model2s.jl

This file contains the lines:

import SearchLight.Migrations: create_table, column, columns, pk, add_index, drop_table

function up()
  create_table(:model1smodel2s) do
    [
      primary_key()
      column(:model1s_id, :int)
      column(:model2s_id, :int)
    ]
  end

So it imports pk, but tries to use primary_key.

Error stacktrace

julia> SearchLight.Migrations.all_up!!()
[ Info: 2022-01-14 11:45:16 SELECT version FROM schema_migrations ORDER BY version DESC
[ Info: 2022-01-14 11:45:16 SELECT version FROM schema_migrations ORDER BY version DESC
┌ Error: 2022-01-14 11:45:16 Failed executing migration CreateRelationshipTableModel1sModel2s up
└ @ SearchLight.Migration ~/.julia/packages/SearchLight/B9d2o/src/Migration.jl:300
ERROR: UndefVarError: primary_key not defined
...

To reproduce
Should be fairly obvious...

Expected behavior
It imports and uses the same function (pk or primary_key), and the relationship table is created.
