Markdown Extensions: Steps

[trueberryless]

I would like to propose to add a new Markdown extension to Vitepress which renders an ordered list with additional styling to make them look like steps that need to be followed, which often occurs in documentation.

An example of such a feature in other documentation frameworks would be Starlight's Steps component.

• I am willing to submit a PR with this feature when the discussion concludes and the feature is approved.

Yeah can be added. Syntax can be container-like I guess:

::: steps

1. foo
   bar

2. baz
   qux
