graphql-alt: Query.packageVersions

## Description

Add support for

- `Query.packageVersions`,
- `MovePackage.packageVersionsBefore`, and
- `MovePackage.packageVersionsAfter`,

similar to the equivalent `Object` APIs, but using package versioning
schemes (and only working for objects that are packages).

## Test plan

New E2E tests:

```
sui$ cargo nextest run -p sui-indexer-alt-e2e-tests
```

Update schema tests:

```
sui$ cargo nextest run -p sui-indexer-alt-graphql -- schema
```
