Impl Deref<Target = str> for yew::virtual_dom::Key

[faulesocke]

Describe the feature you'd like
Please impl Deref<Target = str> for yew::virtual_dom::Key. This would allow code like the following:

some_function(&key)

instead of

some_function(&key.to_string())

Questionnaire

• I'm interested in implementing this myself but don't know where to start
• I would like to add this feature
• I don't have time to add this right now, but maybe later
