Pessimistic version constraint operator misused

[ellnix]

In the gemspec, we specify the dependency on the meilisearch-ruby gem as:

  s.add_dependency 'meilisearch', '~> 0.28'

However, the twiddle-wakka (~>) operator is not meant only for minor versions, its behavior depends on how you specify the version. ~> 0.28 will grab anything >= 0.28 and < 1, while ~> 0.28.0 will grab >= 0.28.0 to < 0.29.

This essentially means that our constraint does not prevent old versions of the meilisearch-rails gem from grabbing newer versions of meilisearch-ruby.

This has already caused issues with our communication failure in shipping meilisearch-ruby 0.30 with the renamed top level module, I wrongly believed that wouldn't be an issue since this rails gem would be frozen in place. See #347 (comment) .
