Feat: Ensure docs site works with OAS (@W-18483003@)

[joeluong-sfcc]

This PR updates the docs to reflect the new OAS changes in the Isomorphic SDK. Due to the restructuring of the SDK, there's additional complexity to navigating the docs site. A section has been added in the README for clarity.

This is almost identical to the isomorphic SDK site, however, since there are a large number of APIs, when you navigate to an API class, the right sidebar to navigate through the API classes disappears and you have to click on Globals to navigate back. A section was added in the README to describe this difference.

Synk CI check will be fixed in another PR.

To test this PR:

1. git checkout ju/oas-docs
2. run open docs/index.html
3. navigate the docs site

Originally upgraded to fix a linting issue, but the linting issue is not appearing any longer so dropping these dependencies down to keep it in alignment with commerce-sdk-isomorphic

Can we removed quotes around "index", "types", "version"?
Does "types" included common types shared between classes?
What us "version" module? Can we add few more details in the docs?
