Two block tall flowers are part of #minecraft:sword_efficient even though one block tall flowers aren't

The bug

The tag #minecraft:sword_efficient is intended for use on blocks which take an amount of time to mine, and a lesser amount when broken with a sword. It has no effect on blocks which are broken instantly, however, despite this, it is applied to two-block-tall flowers. This is pointless, makes datapack creation confusing, and bloats the F3 screen.

One-block-tall flowers have the correct behaviour: they are not part of this tag.

How to reproduce

1. Look at a flower

2. Press F3

3. Look at the tags

Expected results

The sword tag wouldn't be there.

Actual results

It correctly isn't there for one block tall flowers, but incorrectly is for two block tall flowers.

How to fix

Remove all two block tall flowers from this tag, as it makes no sense for them to be there.
