fix: bump minimum web-sys to 0.3.70

Reported on discord.

This is a sneaky error introduced since aa21119 (two years ago). It can cause a compile error when somebody picks up a 2 year old project again.

Thanks. Note, this was part of the initial fix but seems to got swept under when they got converted to workspace deps, A quick scan reveals the following packages that also got their patch version unbumped: serde, thiserror, reqwest, js_sys. The only one of those that I can see causing a similar issue is js_sys that is a dep of web_sys and gets pull in via this regardless.

I see. Actually my mistake
