Fix english strings consistency
Description
Some terms were used inconsistently.
Hello @SoftFever, I didn't open all these MRs at once, they were opened on different days along the last weeks. They are taking a long time to get in, so they accumulate. And that's also why they break the builds, other merges enter first and cause conflicts, and sometimes they break when I fix the merge issues.
I found more problems with the text, I am changing this to draft until I fix them all as requested by @SoftFever.
I am done with this one. @SoftFever, can you merge this before regenerating the .po files to avoid the conflicts?
Rebased to main. Again.
Rebased to the latest main branch and added the changes to the new lithuanian translation.
Another rebase to main, to fix conflicts.
