Revert packages to use nominal package versions

[dcousens]

Alternative to #9266
Reverting #9112 and other pull requests, and seeking an alternative strategy for working with workspace package versioning.

This stops examples/ from generating CHANGELOG.md and version bumps

@flexdinesh 💛 but we don't add this field for any of the other examples, that is what git is for

@kennedybaird if you can follow up this work with a pull request that resolves the fixPrismaPath and bump the CodeSandbox configurations to use Node 20, that would be really appreciated.

I think this configuration works well with pnpm changeset version, which is what we are using for release; and keeps the maintenance about the same.
