/**
 * We don't want to allow `workspace:^` in our dependencies because our current release branch
 * strategy only allows for patch changes in the release branch and minors elsewhere.
 *
 * If we were to allow `workspace:^`, then the follow scenario causes issues:
 *   - Suppose we have a Foo and a Bar package and Bar depends on Foo.
 *   - at T0 we cut a release/1.1.x branch and ship Foo@1.1.0, Bar@1.1.0
 *   - at T1 we cut a release 1.2.x branch and ship Foo@1.2.0
 *
 * If we have `workspace:^` in our deps, a user that already has `Bar@1.1.0` in their package.json
 * could update their dependencies without updating Bar (say via pnpm update) and Bar's dependency
 * on Foo @ `^1.1.0` would be satisfied by the shipped `Foo@1.2.0`.
 *
 * Using `workspace:~` prevents this as `~` can only resolve patch changes.
