Use Carbon link icon for header permalinks

[mzuliani-ibm]

Feature and motivation

Is there an easy way to use the Carbon icon instead of a unicode character for getting the URL for a within-page header link?

It doesn't have to autohide like Carbon Gatsby's AutolinkHeader

Current configuration in mkdocs.yml

markdown_extensions:
  - toc:
      permalink: "¤"

Usage example

Might be less obtrusive than the current implementation: ¤

What is the carbon icon?

[mzuliani-ibm]

Gatsby uses the <Link /> Carbon icon.
In Carbon Gatsby the icon only appears on hover over the heading, in the left margin, using the $link-01 color. (Blue)

Should be able to do this using something like the approach here: squidfunk/mkdocs-material#3535
