meta: Actually sync yarn.lock

[DeeDeeG]

This should make yarn.lock stable across multiple installs.

(Not sure why this diff wasn't part of the npm bump, but who knows?)

Note, this technically overlaps with #57, but I think this is worth merging on its own.

This change is also committed in #57, but it is arguably a bit off-topic/out-of-scope there (?) and there is no diff between this branch and that one in terms of yarn.lock, so there should be no merge conflict if this one merges first.

#57 is currently a WIP PR with multiple changes needing to be done, and/or its scope reduced significantly to be mergeable, and so I don't think it'll be ready right away, whereas this is a really narrow one-file diff with a small diff at that.

If possible, I'd like to get the present PR merged here before syncing back to the core Pulsar repo again.

CI looks great, diff looks good, lets get this one merged!

Thank you for the review, merging this one, PR at core to bump the ppm submodule soon!
