org-transclusion-make-from-link should not add transclusion link in next org heading

[josephmturner]

I find the behavior of org-transclusion-make-from-link to be unexpected:

Given

* Heading A
Some text here
[[./link to transclude.org]]
* Heading B
Some more text here

With point on the link, if I run org-transclusion-make-from-link, I would expect to see:

* Heading A
Some text here
[[./link to transclude.org]]
#+transclude: [[./link to transclude.org]]
* Heading B
Some more text here

but instead the buffer shows:

* Heading A
Some text here
[[./link to transclude.org]]
* Heading B
Some more text here
#+transclude: [[file:./link to transclude.org]]

Would you be open to stopping upon reaching an org heading?
