docs code block formatting

`console` type code-block is designed mainly for examples of the console commands with the output.

If it's just a shell script with comments, then `console` only gets in the way - e.g. if you try to select a console code block manually, you won't be able to select comment symbol `#` at the beginning of the command making code unrunnable if you try to copy and run it. I've replaced it with `bash` or `bat` (for Windows) code blocks where `console` wasn't necessary.

I've also removed `$` symbols at the beginning of the commands if it's not a `console` code-block - since otherwise it just breaks "Copy Code Block" because you copy unrunnable code.

-.. code-block:: console
+.. code-block:: bash
 
-    $ cd /path/to/ifcopenshell/src/blenderbim/docs/

 You will now have a local webserver running hosting the documentation.
