Fix Grafana ML icon (#73813)

`grafana-ml` was added to the `availableIconsIndex` object in
<commit> but no corresponding SVG was added, nor was the Icon
bundle updated.

This commit adds the real Grafana ML icon as gf-ml.svg, renames
the key in the availableIconsIndex accordingly, and updates the
Icon bundle using the documented script. Note that the name
was changed to `gf-ml` rather than `grafana-ml` because otherwise
the wrong directory is used (unicons rather than custom).

The main motivation for adding this is because plugin extensions
need to specify a valid icon name, and we want to use the Grafana ML
icon for our extensions, which requires the icon to be part of
core Grafana.
