Offer mxschmitt/action-tmate/detached for convenience

The `mxschmitt/action-tmate/detached` Action does exactly the same as
the `mxschmitt/action-tmate` Action, except defaulting to detached mode.

This will come in handy in the increasingly many cases I seem to
experience of late where I want to use the detached mode without the
price of adding a `with` section.

Not a big price, but it accumulates.
