What is your expected behavior?
I should not be seeing the DEP errors

Git repository to reproduce the issue:

Ruby version used:
$ ruby -v
ruby 2.5.5p157 (2019-03-15 revision 67260) [x64-mingw32]

Jekyll version used:
$ jekyll -v
jekyll 3.8.5

Gemfile:
group :jekyll_plugins do
gem 'jekyll-algolia', '~> 1.0'
end

_config.yml
algolia:
application_id: ID_HERE
index_name: jekyll
search_only_api_key: KEY_HERE

Start by reproducing `bundle exec jekyll algolia` with Ruby 2.5.5, Jekyll 3.8.5, the shown Gemfile, and `_config.yml`. Trace the jekyll-algolia entry point that processes documents and identify the source of the `Document#name` deprecation. Done means indexing completes without these deprecation messages.
