Merge pull request #26773 from MaximSmolskiy:improve-robustness-for-ellipse-fitting 
Improve robustness for ellipse fitting #26773

### Pull Request Readiness Checklist

Related to #26694 

Current noise addition is not very good because for example it turns degenerate case of one horizontal line into degenerate case of two parallel horizontal lines

Improving noise addition leads to improved robustness of algorithms
