feat(linter): add eslint/no-unneeded-ternary rule

[cdrikd]

Implement the eslint/no-unneeded-ternary rule.

I have a question, where to put the options of the rules ? in the examples or in a specific chapter "Rule options" before examples ?

It's my first rust contribution, I just start to learn the language so don't hesitate to tell me enhancement.
