DOC: Improved pandas.plotting.bootstrap_plot docstring (pandas-dev#20166)

* Improved documentation on bootstrap_plot

* Improved documentation on bootstrap_plot

* Doc bootstrap_plot: Fixed some comments on pull requests

* Added reference to wikipedia

* Changed kwds for **kwds

* Removed ** from kwds becuase of validation iuses

* Fixed forgotten break line. I think that the kwds paramater now fits what expected @TomAugspurger. If not, sorry and indicate how it should be

* Fixed warnings on compilation

* Moved reference to extended description

 def bootstrap_plot(series, fig=None, size=50, samples=500, **kwds):

+    """
+    Bootstrap plot on mean, median and mid-range statistics.
+
+    The bootstrap plot is used to estimate the uncertainty of a statistic
+    by relaying on random sampling with replacement [1]_. This function will
+    generate bootstrapping plots for mean, median and mid-range statistics
+    for the given number of samples of the given size.

     Parameters
     ----------
-    series: Time series
-    fig: matplotlib figure object, optional
-    size: number of data points to consider during each sampling
-    samples: number of times the bootstrap procedure is performed
-    kwds: optional keyword arguments for plotting commands, must be accepted
-        by both hist and plot
+    series : pandas.Series
+        Pandas Series from where to get the samplings for the bootstrapping.
+    fig : matplotlib.figure.Figure, default None
+        If given, it will use the `fig` reference for plotting instead of
+        creating a new one with default parameters.
+    size : int, default 50
+        Number of data points to consider during each sampling. It must be
+        greater or equal than the length of the `series`.
+    samples : int, default 500
+        Number of times the bootstrap procedure is performed.
+    **kwds :
+        Options to pass to matplotlib plotting method.
 
     Returns
