Changes proposed in this Pull Request:

This PR adds 3 new subscribe patterns. These are slightly different from the previous ones. They use templateLock: all on the main Group and lock:{remove:false} on the heading and copy.

This means that these patterns are kind of locked yet there's still some flexibility with its customisation.

How to test the changes in this Pull Request:

1. Switch to this branch
2. Insert the various patterns to a page and/or a prompt

These new patterns are really looking nice! 🎉

The template locking seems to work well in my testing -- I was able to remove and edit heading, paragraph, and image blocks, and swap the image in the media & text block, but not actually delete the media & text, columns or contact blocks.

The inability to add blocks tripped me up a bit, even though I knew the templateLock was in place -- it felt a little weird that I couldn't add a second paragraph, or re-add one once I deleted it. This functions as expected, though, and AFAIK this is as nuanced as locking gets right now.

I don't think this is a blocker, but it might be a good thing to keep tabs on and see what the general feedback is -- I could be finding problems that won't come up in the real world 🙂 And worst-case, the lock can be removed by using the code editor (the other way is to "Ungroup" the group block, but that's not a good idea for these!).

re-add one once I deleted it

Yep that's kind of the downside of templateLock. But I think this is better than allowing user to mess with the pattern 😃
