"add as untranslatable" button

[xuars]

Describe the problem

After saving an untranslatable term without adding it to the glossary, I get the error message:
"The translation has been saved, however there are some newly failing checks: Unchanged translation".

Solution brainstorm

Make it easier to add the term to the glossary as an untranslatable term with a button in this error called "Add to glossary as untranslatable term", saving time for the translator.

When adding term to glossary there is a checkbox to mark the term as non-translatable...

I mean to add a button in the error to add the complete string translation to the glossary without having to create the glossary entry first, in case the translator forgot to do it, and pressed continue.

I mean like in the image above.
This is particularly useful for mobile users, as they have to scroll almost to the bottom of the page to add it to the glossary, so this button will save them time.

The untranslatable flag is currently per term, not per translation, see #12815
