Add docs for `data-turbo-method` and `data-turbo-confirm` for `link_to`

Rails 7 ships with Turbo enabled by default. Instead of using
`data-method` and `data-confirm`, Turbo now uses `data-turbo-method` and
`data-turbo-confirm` to perform a link visit with the specified HTTP
method and show confirmation dialog respective.

The deprecated legacy options are documented but the new options are
not.

This commit documents the `data-turbo-method` and `data-turbo-confirm`
for the `link_to` method.

The `button_to` documentation has also been updated to reference the
new `link_to` options.
