[dkilgore-eightfold]

SUMMARY:

Adds localization support to BaseDialog and Dialog

JIRA TASK (Eightfold Employees Only):

ENG-30997

CHANGE TYPE:

• Bugfix Pull Request
• Feature Pull Request

TEST COVERAGE:

• Tests for this change already exist (loc tests)
• I have added unittests for this change

TEST PLAN:

Pull the pr branch and do yarn, then yarn storybook, verify the Dialog stories behave as expected.

Set the Dialog locale to another language and test the go to text as follows (pseudo-code):

import { zhCN } from "@eightfold.ai/octuple/";
<Dialog locale={zhCN} okText={'foo'} />

The ok button text in the Dialog should read 'foo' and the others should use the loc defaults.
