fix(dbt): support projects with saved queries (dagster-io#21441)

## Summary & Motivation

When i upgrade from dagster 1.6.11 to 1.7.3 I am no longer able to use [dbt's saved queries](https://docs.getdbt.com/docs/build/saved-queries) via the [dagster-dbt integration](https://github.com/dagster-io/dagster/tree/master/python_modules/libraries/dagster-dbt). I am now getting a `key error` before any definitions can be loaded by dagster from the dagster-dbt assets example:

For reference `saved_queries` are located in the [dbt's manifest.json schema](https://schemas.getdbt.com/dbt/manifest/v11/index.html#saved_queries)

## The problem

Manifest creation in master (dagster 1.7.3): https://github.com/dagster-io/dagster/blob/master/python_modules/libraries/dagster-dbt/dagster_dbt/utils.py#L255 has changed how the manifest is parsed and no longer picks up saved_queries.


Manifest creation in master (dagster 1.6.11): https://github.com/dagster-io/dagster/blob/release-1.6.11/python_modules/libraries/dagster-dbt/dagster_dbt/utils.py#L243 is the version that currently works for me. It simply gets all keys from dbt's manifest.json with the code`Manifest.from_dict(manifest_json)`


I have added the `saved_queries` key to this branch to fix this up

## How I Tested These Changes

Have tested this locally (editable install) and it allows me to load all definitions including dbt's saved queries.
