docs: update getByText docs (testing-library#123)

Closes testing-library#122 **What**: `getByText` section in the readme. **Why**: The current example is not accurate. **How**: Since the `exact` option is true by default, I use a regular exception with ignore case to find the desired element by text. **Checklist**: - [X] Documentation - [ ] Tests N/A - [X] Ready to be merged - [X] Added myself to contributors table
