[hitori/15-docs: 3/3] help: Make terminology around tagging more consistent

[Philip Withnall <pwithnall src gnome org>]

commit 489db618c7e6af45565d44f7a97f821a7eac0f11

    help: Make terminology around tagging more consistent
    
    The code and various things like the README refer to this as ‘tagging’,
    but the documentation referred to it as ‘highlighting’. The latter is
    quite a general word, so use the former more consistently.

        <p>Hitori is quite similar to Sudoku, in that it takes logical deduction to work out which cells to 
paint out. One strategy is to use

use <key>Ctrl</key>-clicking to
-               highlight all the repeated numbers in each <em>row</em>.</p>
-       <p>Once this is done for the entire board, the cells which have been highlighted both ways are good 
candidates for painting, although not

        <p>Always bear in mind that rule 2 of Hitori means that two adjacent cells can’t both be painted.
