problem support custom primary key

[masukomi]

Description
this builds on #250 BUT if we fix that issue ... we run into the next one

this line

        condition_key = meilisearch_options[:type].primary_key if has_virtual_column_as_pk

calls the primary_key method on the model. Mongoid doesn't have a primary_key method and it seem to be doing anything with the fact that I've added the following to my model. It should be calling my ms_id method but it's hardcoded to call primary_key

meilisearch primary_key: :ms_id

this may actually be an issue that extends beyond mongoid, but i can't test that at the moment.

Expected behavior
call the primary key method i told it to.

Current behavior
it called .primary_key which is a non-existent method.

Task.find('foo')
/Users/masukomi/.rbenv/versions/3.2.0/lib/ruby/gems/3.2.0/gems/meilisearch-rails-0.9.0/lib/meilisearch-rails.rb:650:in `ms_search': undefined method `primary_key' for Task:Class (NoMethodError)

        condition_key = meilisearch_options[:type].primary_key if has_virtual_column_as_pk

Environment (please complete the following information):

• OS: [macOS]
• Meilisearch server version: [e.g. v.1.1.1] (irrelevant though)
• meilisearch-rails version: [e.g v0.9.0]
• Rails version: [e.g. 7.0.4.3]

Following my comment in the previous issue #250 we need to proper test and fix the issues in the MongoId.

I'm going to close this issue because all the MongoDB requests are going to be tracked in the issue #175.
