"Open with Studio" button for Markdown files.

#### Reason/Context
I'm lately advocating for using Studio whenever I want to add a link to an AsyncAPI file in a Markdown file such as Readmes. Thanks to the `?url=` query param, Studio can load most of files (yes, not all of them, see https://github.com/asyncapi/studio/issues/127).

I think it would be awesome to create a new design for a button that says "Open with Studio", with the AsyncAPI logo on the left or similar.

#### Description

To design a button that says something like "Open with Studio", with the AsyncAPI logo somewhere that people can use for linking to AsyncAPI files in their Markdown/HML files.

Some examples:

Start by reviewing the linked button examples and the issue's description of Markdown/HTML usage. Done means a new "Open with Studio" button design, including AsyncAPI branding, that people can use to link AsyncAPI files to Studio.
