[Feature] Execute post_hook after apply_grants and persist_docs

[wilsonkkyip]

Is this a new bug in dbt-bigquery?

• I believe this is a new bug in dbt-bigquery
• I have searched the existing issues, and I could not find an existing issue for this bug

Current Behavior

post_hook is executed before apply_grants and persist_docs

Expected Behavior

post_hook being executed after apply_grants and persist_docs

Steps To Reproduce

Reading the script in https://github.com/dbt-labs/dbt-bigquery/tree/main/dbt/include/bigquery/macros/materializations

Relevant log output

No response

Environment

- OS: Mac OS 15.1 (24B2083)
- Python: 3.11.11
- dbt-core: 1.9.1
- dbt-bigquery: 1.8.3

Additional Context

I have written a few post hooks to compare between the table metadata from BigQuery API (through adapter) and the model properties from the yaml files.

If apply_grants and persist_docs are being run after post_hook, the column description and policy tags will never match the specification in the yaml files.

Of course I can create a custom materialization for my usage. But I am thinking if it will be better to run post_hook after apply_grants and persist_docs in general?
