Improve the DFW admin pointer text

[johnbillion]

I don't think the text in the admin pointer for DFW is good enough.

Start typing, and the other elements fade away so you can focus. Move your mouse out of the editor to reveal everything again.

At the point when it's first shown to a user, DFW is not enabled so it doesn't make sense. Also, "the other elements" lacks context.

I suggest we change it to this:

With distraction free writing mode enabled, everything surrounding the editor fades away when you start typing. Move your mouse out of the editor to reveal everything again.

Or, we can make it more of a call-to-action with this:

Enable distraction free writing mode and everything surrounding the editor will fade away when you start typing. Move your mouse out of the editor to reveal everything again.

Uses the call-to-action variant.

The patch indicates an issue introduced in [30574]: translatable strings cannot be concatenated like that. That's why this pointer text is missing from GlotPress and the latest .pot files.

[ianmjones]

Removed concatenation from string.
