Add kubectl patch example with quotes on Windows (kubernetes#18853)

* Add kubectl patch example with quotes on Windows

When running the `kubectl patch` example, on Windows systems you get an
error when passing the patch request in single quotes. Passing it in
double quotes with the inner ones escaped produced the desired behavior
as is in the example given for Linux systems. I've added a small note
for Windows users to have that in mind.

* Use Hugo note shortcode

Windows note is placed inside a
[shortcode](https://kubernetes.io/docs/contribute/style/style-guide/#shortcodes)
to be consistent with the style guide.

* Remove shell Markdown syntax

I've removed the shell syntax from the Windows example and have changed
the description to be the same as the one used in
[jsonpath](https://kubernetes.io/docs/reference/kubectl/jsonpath/)
document to be more consistent. The jsonpath example uses cmd syntax,
though it is note inside a note shortcode, therefore I've opted out of
using any syntax as it seems to break rendering inside the shortcode.

* Add cmd markdown syntax and fix order list

I've tested this locally with `make docker-serve` on my Linux machine
and finally things are looking better, I've managed to address these two
issues:

- the Windows example is now inside `note` shortcode and also the cmd
syntax renders correctly on the page

- the list of steps broke after the first one, I've indented a paragraph
and now the steps are in the expected order

* Remove command prompt from example

According to the [style guide](https://kubernetes.io/docs/contribute/style/style-guide/#don-t-include-the-command-prompt), the command prompt should not be included when showing an example. This commit removes it for consistency with the style guide.
