Document API resources methods

[andrii-bodnar]

The Autogenerated online documentation was added in #32. In this PR only the Bundles, Projects, Storage, and Source Files resources were documented.

Example of the method annotation:

https://github.com/crowdin/crowdin-api-client-ruby/blob/main/lib/crowdin-api/api_resources/bundles.rb#L6-L8

We need to add annotations for the rest API resources:

• dictionaries.rb
• distributions.rb
• glossaries.rb
• labels.rb
• languages.rb
• machine_translation_engines.rb
• reports.rb
• screenshots.rb
• source_strings.rb
• string_comments.rb
• string_translations.rb
• tasks.rb
• teams.rb
• translation_memory.rb
• translation_status.rb
• translations.rb
• users.rb
• vendors.rb
• webhooks.rb
• workflows.rb

---

API reference:

• Crowdin API reference
• Crowdin Enterprise API reference

Each API resource documentation can be delivered in a separate PR. Also, it's a good idea to join some resources into one PR.
