fix: oas 3.1 schema expand/collapse not working on initial render

[scottohara]

Description

The setExpanded() and setCollapsed() callbacks were missing pathMutator in the useCallback() dependency array, meaning that there was a race condition on initial render when configured with defaultModelRendering: "model".

Switching from Schema -> Example Value -> Schema worked around the issue, but this PR fixes it so that the schema expansion works on first render without the workaround.

Motivation and Context

Fixes #10628

How Has This Been Tested?

Manually tested in local dev server by configuring the dev-helper-initializer.js file as follows:

const ui = SwaggerUIBundle({
  url: "https://gist.githubusercontent.com/seriousme/55bd4c8ba2e598e416bb5543dcd362dc/raw/cf0b86ba37bb54bf1a6bf047c0ecf2a0ce4c62e0/petstore-v3.1.json",
  defaultModelRendering: "model",

Also added an e2e test to ensure that the expand collapse works on initial render.
