Replace jquery-ujs with @hotwired/turbo

Replace our client-side dependency on `jquery-ujs` with
[@hotwired/turbo][] through the `turbo-rails` gem.

Other than swapping some [config/importmap.rb](./config/importmap.rb)
entries, this commit replaces `[data-confirm]` attributes with
`[data-turbo-confirm]`, and `[data-method]` attributes with
`[data-turbo-method]`.

In an effort to minimize the diff, this commit *does not* replace the
`link_to` calls made with `method: :delete` with [button_to][] calls.
Ideally, they'd utilize `button_to` to render a `<form>` element for the
destructive action.

In the future, once that change is complete, the `data: {turbo_method:
:delete}` attributes can once again be passed as `method: :delete`
options.
