Add line-specific review feedback to correct deployment wording in auth flows docs

[Copilot]

Provided a focused review on PR #770 for deployment-wording accuracy in the new authentication flows documentation. The review flags statements that read as absolute (“no redeploy”) where the page itself documents exceptions for product-hosted pages.

• Problem focus

  • Audited new auth-flows content for wording that could overstate redeploy-free behavior.
  • Targeted only deployment-semantics accuracy, not style or structure.

• Line-specific review comments delivered

  • src/content/docs/authenticate/about-auth/configure-authentication-flows.mdx:16
    Replace absolute metadata claim (no app redeploy required) with qualified wording.
  • .../configure-authentication-flows.mdx:41
    Replace universal statement with “many changes” phrasing.
  • .../configure-authentication-flows.mdx:43
    Clarify that Kinde-hosted changes can avoid app redeploys, while product-hosted pages still require deployment.

• Suggested wording pattern

- With Kinde, you can reconfigure authentication flows without redeploying your application.
+ With Kinde, many authentication flow changes can be made without redeploying your application.

- ...not by shipping a new build of your app every time.
+ ...with Kinde settings, hosted page design, or code running in Kinde—while product-hosted pages still require deploying your app.
