dbt fusion unexpectedly stopped compiling correctly on the latest version.

```
dbtf --version
dbt-fusion 2.0.0-preview.166
```
When compiling, the profiles.yml fails to load:

```
dbtf compile
dbt-fusion 2.0.0-preview.166
Loading profiles.yml

**Expected behavior**

This works properly in the previous version (164)

```

Seems like yaml anchors not being recognized is the issue. Our profiles.yml has this for dev:

```
account: &account
type: snowflake
account: [redacted]
dev:
<<: *account
# Credentials
user: "{{ env_var('SNOWFLAKE_USERNAME') }}"
role: data_developer
private_key_path: ../dbt_auth.pem

# Runs Config
database: sandbox
schema: DBT_PLACEHOLDER_SCHEMA
threads: 16
warehouse: "{{ env_var('SNOWFLAKE_WAREHOUSE_XS') }}" # Default to xs warehouse
client_session_keep_alive: False

```

New version will compile correctly if type and account are moved into the the dev profile instead of using anchors.
