"Not Committed Yet" is not translatable

In Qt Creator, I have checked the "Instant Blame" box in Preferences > Version Control > Git.

When I write new code and save the file, I see a message on the right of the code line that writes "Not Committed Yet YYYY-MM-DD" (see the attached screenshot). "Not Committed Yet" is not translated and I did not find this string in the source code (I just see this string as a comment in gitclient.cpp). So it is not clear to me where this string comes from.
Could you allow this string to be translated?
