Title: DOC: fix 2 covariance examples rst math markup.

Some formulas in plot_mahalanobis_distances and
plot_robust_vs_empirical_covariance were not correctly
rendered by sphinx as some characters were not properly
escaped. This is fixed by setting the docstrings as
raw string using r""".

There was also missing braces for the number of features
and samples subscript.
