PlotlyJS.savefig (v0.18.8) not working on M1 mac running Julia 1.7-1.9 (arm64)

When I tried to save a jpeg figure using PlotlyJS, it fails on M1 mac running Julia v1.7. The same example runs fine on a Intel mac:

```
using PlotlyJS

function linescatter1()
trace1 = scatter(;x=1:4, y=[10, 15, 13, 17], mode="markers")
plot([trace1])
end
linescatter1()

testio = open("test.jpg", "w")
PlotlyJS.savefig(testio, linescatter1(); format="jpeg");
close(testio)
```

The error output is:
```
julia> PlotlyJS.savefig(testio, linescatter1(); format="jpeg");
