Merge bitcoin-core#406: Handle new added plurals in bitcoin_en.ts

2b3d8f3 qt: Handle new added plurals in bitcoin_en.ts (Hennadii Stepanov)

Pull request description:

  This step was missed. See [`translation_process.md`](https://github.com/bitcoin/bitcoin/blob/master/doc/translation_process.md#handling-plurals-in-source-files).

  Transifex is smart enough to handle `%n` in strings as a plural form. Therefore, only two English strings are broken in the GUI on master (and in 22.0).
