Correction of map representation in RESP2 (#2587)

In the protocol spec, the description of how maps are represented in RESP2 is incorrect. "Maps in RESP2 are represented by arrays, in which each element is a key-value tuple. Each tuple is an array with two elements, these being the key and the value." This is not true. A map in RESP2 is represented as a flat array containing the keys and values, not nested arrays. The description is updated. Co-authored-by: Viktor Söderqvist <[email protected]>

 RESP2 doesn't have a map type.
-Maps in RESP2 are represented by arrays, in which each element is a key-value tuple.
-Each tuple is an array with two elements, these being the key and the value.
+A map in RESP2 is represented by a flat array containing the keys and the values.
+The first element is a key, followed by the corresponding value, then the next key and so on, like this:
+`key1, value1, key2, value2, ...`.
