Change address in package.metadata.

[ccqpein]

I was using this template and looks like I should change site-addr to site_address. Or I would get the

thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: ConfigError("missing field `site_address`")', src/main.rs:10:62

Thanks — this one is actually a last small inconsistency between cargo-leptos and leptos itself. It should be site-addr but there's one place in leptos that still needs to change it.

Thanks. @gbj feel free to change it. I am still playing around with leptos.
