Incorrect name for localization variables in breath2 theme

Therefore, the translation display does not look correct for some lines.

I fixed for the theme breath2 only, those files that need it. The correct variables are now used. Display verified for Russian language (ru) on KDE Plasma 5.17.5. Archive with the corrected version is breath2.zip.

For the right approach, the version of the breeze theme from KDE Neon 5.18.2 is taken. Just in case, I attach breeze.zip theme.
