feat: support dbt model versions

[henriblancke]

Hi, I'm adding support for dbt model versions. We rely on versioning heavily and would love for dbt-osmosis to support it. Thanks 🙏

Looks great, really nice and thx for the contribution!

I suspect we will need to update this too
https://github.com/z3z1ma/dbt-osmosis/blob/v1.1.9/src/dbt_osmosis/core/osmosis.py#L1689
If we want the unrendered version of information to be usable such as {{ docs() }} in versioned models, otherwise we will inadvertently hydrate them.

In fact, looking closer _get_node_yaml (the function above) should probably take a kwarg that determines if its read-write or read-only
And that function should be the sole place where we grab a mutable "slice" of the deserialized data object. This would make our code more DRY in one of the last spots.
Its not incumbent on you to do unless your bored or really feeling it :)
Otherwise I will try to get to it this week and we can merge this as-is. LMK either way. I'll just want the above tackled before I cut a patch release.

Hi @z3z1ma thanks for the quick feedback. I was hoping to have more time this week to tackle your suggestion but it looks like its shaping up to be a busy week. I can probably take a closer look either during the weekend or next week 🤞. Maybe we can tackle it as part of a different PR? Thanks again!

Sure thing, I'll merge it now. Thanks again.
