ci: update yarn.lock as part of nx release (#2426)

## Summary:

`nx release` will bump local packages that are referenced in our lock
file, thus invalidating the lock file till we run `yarn install` again.
Let's run `yarn install` as part of our generator

## Test Plan:

Tested by cherry picking this commit to a local `0.77-stable` branch,
creating a version plan, and running `nx release --dry-run`. `yarn
install` was run.
