[ENH]: SysDb should return lineage, version file paths and root collection ID on collections (#4557)
## Description of changes See title. Needed for garbage collector tests. ## Test plan _How are these changes tested?_ Updated existing Go tests to cover changes on Go side. Rust changes will be consumed in a future PR. ## Documentation Changes _Are all docstrings for user-facing APIs updated if required? Do we need to make documentation changes in the [docs section](https://github.com/chroma-core/chroma/tree/main/docs/docs.trychroma.com)?_ n/a
