fix: broken star history chart

[Dessalines39394]

The star history chart in the README is currently broken, as the stargazer data source it depends on has been restricted and no longer serves the chart. This change points the chart at a working provider so the star history renders correctly again.

Before I merge this, I might appreciate getting a bit of visibility into dera.page, which seems to be fairly young.

For example, the website advertises that "GitHub's Stargazer API shutdown doomed the original, but this fork keeps star history alive from a different data source", but doesn't say what this "different data source" is. (Or why the original star-history.com wouldn't just use that data source.)

I'd also appreciate knowing what your affiliation to Mubelotix is, if any. I don't mind self-promotion per se, especially for young projects trying to get off the ground, but I do appreciate disclosure so it doesn't feel like something is being intentionally concealed from me. I say this from noticing you have over 100 forks of various public repositories, and a spot check suggests they're all for this particular change, e.g. royshil/obs-backgroundremoval#948 as an example. I think the privacy concerns there are valid here too.

I'm sorry if I come across as unnecessarily suspicious. (I am a longtime Arch user and the recent attacks on the Arch User Repository have left me more paranoid than usual.)
