mutex issues

I'm trying to get the latest version of pushkin-cli to run. It's failing on install site:

`Problem installing dependencies for api Error: Command failed: yarn --mutex network install

Note that I had to reinstall yarn because my computer apparently forgot it. Which is strange in its own right...

Looks like this was an issue with yarn. We are using version 1, but current version is 3. It may be a lot of work to migrate and we might want npm instead, so we're going to put off worrying about this.

I still occasionally get this error with install site and install experiment. It seems to happen pretty randomly -- maybe it has to do with internet connection? If it happens with site, you can delete everything in the site directory and try again. Usually it will work on a second try. If it happens with experiment, you can use the remove experiment to delete the half-installed experiment.

EDIT: One situation where I haven't experienced this error at all is testing in Codespaces. We have setup instructions here. You can make a Codespace from whatever branch you're working on and create a folder called "testing" (already gitignored) where you put your test site.
