Add missing strings.

Hi @love-linger

I don't get the "Likes" part in the Text.Configure.CommitMessageTemplate.BuiltinVars string, can you provide a little more context about what are they being used for? So I can translate them in a more accurate way.

Examples:

A) I "Like" this file names?
B) This file name is "like" the other one?
C) You are not even close.

That is a help message for variables, that can be used in text. Obviously, it explains, that pure_ variables contains the same data, as non-pure_, but only filenames, instead of full paths.

So it's like using "as"?
Example: "Shows/treats pure filenames like/as non-pure filenames".
