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.

 `Sphinx <https://www.sphinx-doc.org/en/master/>`_. First, install Sphinx and
 dependencies:
 
-.. code-block:: console
+.. code-block:: bash
 
-    $ pip install sphinx
-    $ pip install sphinx-autoapi
-    $ pip install sphinx-copybutton
-    $ pip install furo
+    pip install sphinx
+    pip install sphinx-autoapi
+    pip install sphinx-copybutton
+    pip install furo
 
 Now you can generate the documentation:
 
-.. code-block:: console
+.. code-block:: bash
 
-    $ cd /path/to/ifcopenshell/src/ifcopenshell-python/docs/
-    $ make html
-    $ cd _build/html
-    $ python -m http.server
+    cd /path/to/ifcopenshell/src/ifcopenshell-python/docs/
+    make html
+    cd _build/html
+    python -m http.server
 
 You will now have a local webserver running hosting the documentation.
