Review and update vocabulary

[smalluban]

• Remove tooltip from "Trackers blocked", "Tracker modified"
• In Settings -> Trackers, change "entities" to "activities" (needs translation)

did you create the translations @smalluban? can I already review?

[smalluban]

In our current process, the translations are made (pushed automatically) when the new release candidate is created by the script.

Few advantages:

• Smaller tasks with new phrases are grouped, so we don't have to touch translations every day
• We can avoid conflicts in the file, as the translations are in one single file, which if updated often, can lead to conflicts (if changed at the same time)
• Historically, we needed a threshold in the number of new phrases to order new translations

The phrases will be updated automatically when we create a new release. Usually, it's Monday. I'll let you know.

@mdsandu There is one new phrase in the Transifex (pushed with the #1739)

Mind that not all listed activities are trackers, that is not all of them collect personal data.
