TST: Re-generate SVG files that use fonttype='none'
We currently special-case the SVG converter depending on if it usedfonttype='none', and use one that has our base fonts available. However,this is not based on the rcParam setting (because we don't have that atconversion time), but on whether the SVG text contains the font styling[1]. This check for styling uses the _current_ version, which waschanged way back in#19253.These files were never re-generated though, and used the old version ofthe style, meaning the expected images never triggered the specialconverter. The result images are written with the current style, and_do_ trigger the special conveter.Evidentally, this never was a problem for most developers, becauseeveryone had DejaVu Sans installed globally, so the expected imagesmatched. However, on the clean macOS CI, it's not installed globally, sothe expected images get converted with the wrong font, and the testfails.[1]https://github.com/matplotlib/matplotlib/blob/de1102668dbc0694e98653bd17641e9d99394e57/lib/matplotlib/testing/compare.py#L303
