Add option to open tours automatically

Planning for future target

I started an issue fork with a working version of @ksenzee's code. I had to make a couple of small revisions to get it working on a Drupal 10.4 instance as a custom module.

It still needs some tests, but it got me wondering about architecture. Do you want this as a submodule or integrated directly into Tour. I could make a case for either.

@smustgrave, do you have a preference?

I'd want to be configurable either way so it can be turned off or on easily.

After messing with this a bit more, I have the tests for tourauto passing, but there is a failure to the tour tests in 2.0.x.

It seems like a tip that should be created in tests/src/Functional/TourTest.php on line 202 is not being created correctly due to a typo. I've updated that test in addition to all the changes for the tourauto functionality.

Ugh. That's what I get for formatting my issue summary in an editor with settings to limit the line length to 80. (Laughs)

I have a contrib day coming up Friday I’ll add to my list thanks!

Initial testing seems good to me! Since this is a separate module I'm fine adding now and can fine tune later when more people use it.
