[VSCode extension] First link goes to 404

[tsxoxo]

Right after installing the Xstate VSCode extension there was a popup asking if I want to enable nesting-xstate-typegen-files. I clicked on Learn more and it brought me to this URL which gives a 404: https://stately.ai/blog/nesting-xstate-typegen-files.

That's my first interaction after installing the extension.

Thanks for pointing this out. Fixing here: statelyai/docs#187
