docs: Fix markdown syntax

1) Fenced code blocks's keyword "```" should be placed in row 0, or
markdown interpreter will not recognize it;

2) Add blank line between header and content to produce line break.

     This function is practical for example if you want to compare two lists but
     where items are not in the same order:
 
-    ```lua
+```lua
     luaunit.assertItemsEquals( {1,2,3}, {3,2,1} ) -- assertion succeeds
-    ```
+```
     The comparison is not recursive on the items: if any of the items are tables,
     they are compared using table equality (like as in assertEquals() ), where the
     key matters.
 
-    ```lua
+```lua
     luaunit.assertItemsEquals( {1,{2,3},4}, {4,{3,2,},1} ) -- assertion fails because {2,3} ~= {3,2}
