Font in docs SVGs not displayed correctly on windows

[fohrloop]

For example, the wakepy.Mode Activity Diagram at https://wakepy.readthedocs.io/stable/wakepy-mode-lifecycle.html looks like this:

The reason is that the used font is not installed on the Windows system. Should either:

• Make the text to be paths. This has the upside that the image will look the same on any system, but the downside is that editing the images is much harder, as you need to detect the font in order to add any new text (instead of just copy-pasting a text box and editing it) -- unless the svgs are saved twice; one with text and one with text as paths.
• Make the font to be either universal or add fallback fonts, if that's possible.
