Unwanted styles are being applied to code blocks by the `.highlight` class

#### **Your Godot version:**
Latest (4.0)

#### **Issue description:**
The current `.highlight` styles appear to be applying styles for a specific lexer/language (presumably `shell`) to all code-blocks regardless of their language. Instead, language specific styles should be set in their language specific highlight class (e.g. `.highlight-shell` and `.highlight-powershell`).
- This issue is why the `batch` and `powershell` lexers also have drawbacks. They both are having unwanted styles applied to them from the blanket `.highlight` class.
- Until this issue is addressed, a good solution to prevent unwanted styling is to utilize `.. code-block:: none` which will prevent any styling from being applied to a code-block.

### Example: `.. code-block:: batch` command treated as comment.
``` html

      C:\godot> scons platform=windows target=template_debug arch=x86_32

      C:\godot> scons platform=windows target=template_release arch=x86_32

      C:\godot> scons platform=windows target=template_debug arch=x86_64

      C:\godot> scons platform=windows target=template_release arch=x86_64
