svg.elements.marker.orient - orient="auto-start-reverse" is SVG2 feature; needs compat data

What specific section or headline is this issue about?

Usage notes

What information was incorrect, unhelpful, or incomplete?

The description of the allowed values of the orient attribute of a <marker> element does not provide versioning information. Therefore, the documentation does not help in determining that the value auto-start-reverse is an SVG2 extension.

What did you expect to see?

I would like the "Note" box to explicitly mention that this feature is only supported in SVG2 and later:

Do you have any supporting links, references, or citations?

Orient attribute in SVG 1.1: https://www.w3.org/TR/SVG11/painting.html#OrientAttribute
Orient attribute in SVG 2: https://svgwg.org/svg2-draft/painting.html#OrientAttribute

Do you have anything more you want to share?

This issue is split off from mdn/content#22061 as advised by @queengooborg.
It was first found by the Gitlab user KrIr17 when investigating a versioning issue in Inkscape (open-source SVG editor).

Start with the MDN orient attribute page's Usage notes and compare the SVG 1.1 and SVG 2 Orient Attribute references linked in the issue. Update the relevant compatibility data so auto-start-reverse is identified as an SVG2 feature, then verify that the resulting note is displayed correctly.
