seperate UI text from htnl code to make the module translateable 100 %

Steps to reproduce

try to translate the folllowing strings to arabic. get them accepted and than import arabic translations
https://localize.drupal.org/translate/languages/de/translate?project=var...

You'll see import will fail

Proposed resolution

exclude all html Tags from t() so that only text will be submitted to l.d.o in 9.x

So that for example the first string would be separated in two, then

<div class="jumbotron text-center">
  <p> There are no blog posts now! </p>
  <a class="btn btn-primary hidden-anonymous visible-admin" href="[site:url]/node/add/varbase_blog/"> Add One Now </a>
</div>

will be

#1 There are no blog posts now!

#2 Add One Now

Do this for the rest of translation strings containing <div > or <button> tags, too

If it works, the module could be translated up to 100 %

If not we need to inform core maintainers , again, to fix malformed html filter in api.

Remaining tasks

test if the suggested fix wroks.
