v0.3.0

Lots of adjustments in this new release. The goal is to bridge some of the delta between this SDK and the official JS SDK.

1. Error handling overhaul

When 4xx/5xx errors occur, they no longer return JSON responses to the client method. Instead, they raise an appropriate Notion error.

Example using the new error classes:

def list_users
  client.users.retrieve("invalid-id")
rescue Notion::APIResponseError => e
  puts e.code
  # "object_not_found"
end

2. Namespace updates to match notion-sdk-js

All Notion::Client methods have been updated to match the JS SDK counterpart and align better with the official Notion API documentation. For example,

client.get_users

is now

client.users.list

and so on for all other methods in the SDK. The only method that wasn't changed was client#search, since that already matched the Notion API.
