Fix incorrect position of text widget

While working on rebasing #6172 found this bug.
I think it is regression from #6714

Thank you for reporting this. In my opinion the underlying issue is indeed that the code creates its own container instead of using the getContainer function like the other annotation types, which you address in this PR. It is somewhat of a regression as my PR made this issue visible because it was previously fixed in the web/annotations_layer_builder.js layer whereas it is now all taken care of in the getContainer function in src/display/annotation_layer.js.

I will add this PDF file to my local test suite, which I use for each of my annotation PRs, to avoid future regressions. An advantage of this patch is that it provides some nice code cleanup and more consistency with the other functions.
