Docs & website sphinx errors squished 🌦 (#13488)

* fix scala ndarray docs; remove interpreter style

* fix docs error in kvstore

* remove interpreter format in examples

* remove python indicator for these non-functioning python code blocks; clears a sphinx error

* remove old table that was not being used and was triggering a sphinx error

* get rid of curly braces that was causing a pygments error

* fix ambiguous reference causing sphinx error

* nudging file for CI

 ### Push, Aggregation, and Updater
 
 For any key that's been initialized, you can push a new value with the same shape to the key, as follows:
 
 ```scala
-    scala> kv.push(3, NDArray.ones(shape)*8)
-    scala> kv.pull(3, out = a) // pull out the value
-    scala> a.toArray
-    Array[Float] = Array(8.0, 8.0, 8.0, 8.0, 8.0, 8.0)
+kv.push(3, NDArray.ones(shape)*8)
+kv.pull(3, out = a) // pull out the value
+a.toArray
+// Array[Float] = Array(8.0, 8.0, 8.0, 8.0, 8.0, 8.0)
 ```
 
 The data that you want to push can be stored on any device. Furthermore, you can push multiple
 values into the same key, where KVStore first sums all of these
 values, and then pushes the aggregated value, as follows:
 
 ```scala
-    scala> val gpus = Array(Context.gpu(0), Context.gpu(1), Context.gpu(2), Context.gpu(3))
-    scala> val b = Array(NDArray.ones(shape, gpus(0)), NDArray.ones(shape, gpus(1)), \
-    scala> NDArray.ones(shape, gpus(2)), NDArray.ones(shape, gpus(3)))
-    scala> kv.push(3, b)
-    scala> kv.pull(3, out = a)
-    scala> a.toArray
-    Array[Float] = Array(4.0, 4.0, 4.0, 4.0, 4.0, 4.0)
+val gpus = Array(Context.gpu(0), Context.gpu(1), Context.gpu(2), Context.gpu(3))
+val b = Array(NDArray.ones(shape, gpus(0)), NDArray.ones(shape, gpus(1)), \
+NDArray.ones(shape, gpus(2)), NDArray.ones(shape, gpus(3)))
+kv.push(3, b)
+kv.pull(3, out = a)
+a.toArray
+// Array[Float] = Array(4.0, 4.0, 4.0, 4.0, 4.0, 4.0)
 ```
 
 For each push command, KVStore applies the pushed value to the value stored by an
 `updater`. The default updater is `ASSIGN`. You can replace the default to
 control how data is merged.
 
 ```scala
-    scala> val updater = new MXKVStoreUpdater {
-              override def update(key: Int, input: NDArray, stored: NDArray): Unit = {
-                println(s"update on key $key")
