Some dbt projects are generic and are configured in a way that the
`packages-install-path` is jinja templated. For example:
```
packages-install-path: 'dbt_packages{{ "_" + env_var("dbt_packages_suffix","") if env_var("dbt_packages_suffix","")!="" }}'
```
When attempting to use this with
- `ProjectConfig.install_dbt_deps=True`
- `ProjectConfig.copy_dbt_packages=True`
Users who have this configuration face the following error:
```

```
This is because when we implemented
#1768 we did not
forsee the parameter could be a template.
This PR aims to solve this issue.
Observation: we'll need to release this not only as part of 1.12.0, but
also cherry-pick it and, exceptionally, backport it to v1.10.3 and
1.11.3.
(cherry picked from commit 4a906cd)
