docs: fix EXAMPLES.md typo, duplicate TOC, and stale My Account API gating note

- Fix package name typo: flutter_auth0 → auth0_flutter in Credentials
  Manager custom implementation section
- Remove duplicate partial TOC block (lines 59–82 re-listed Web Auth
  section headings that were already in the full TOC above)
- Clarify My Account API setup note: the gating requirement is MRRT
  (Multi-Resource Refresh Tokens), not the My Account API itself —
  the old note incorrectly implied the API feature itself needed to be
  enabled by support, which is no longer accurate
