fix: Reduce openfeature lower bound to 1.13 instead of 1.14 (#38)

**Requirements**

- [x] I have added test coverage for new or changed functionality
- [x] I have followed the repository's [pull request submission
guidelines](../blob/main/CONTRIBUTING.md#submitting-pull-requests)
- [x] I have validated my changes against all supported platform
versions

Tracking was added in 1.13.0 so we can move the under bound from 1.14.0
(current minor version as of now) to 1.13.0
