Dbt-clickhouse

Bug Fixes
- Requirements and tests upgraded to include Python 3.12. Closes https://github.com/ClickHouse/dbt-clickhouse/issues/264
- Model settings were not working correctly for custom materializations. Thanks to original dbt-clickhouse [silentsokolov](https://github.com/silentsokolov)
for the PR!

Improvement
- Adds support for materializing ClickHouse dictionaries. Thanks to [Rory Sawyer](https://github.com/SoryRawyer) for the contribution!
See his excellent [tests](https://github.com/ClickHouse/dbt-clickhouse/blob/main/tests/integration/adapter/dictionary/test_dictionary.py)
for example usage.

Bug Fixes
- Fixed an [issue](https://github.com/ClickHouse/dbt-clickhouse/issues/231) where passing settings to on view creation didn't work.
- The `dbt test` command with a LIMIT clause were broken due to parsing error when having settings in the query ([issue](https://github.com/ClickHouse/dbt-clickhouse/issues/223)).
We added a dedicated limit placer, that takes into account the settings section (using a comment flag `-- end_of_sql` within the query).

Bug Fix
- Fixed an issue where Materialize Views would break with a custom schema. Thanks to [Rory Sawyer](https://github.com/SoryRawyer)
for the PR!

Bug Fixes
- Some models with LIMIT clauses were broken in recent releases. This has been fixed. Thanks to
[ptemarvelde](https://github.com/ptemarvelde) for the PR!
- It was possible for incremental models with the delete+insert strategy to fail if ClickHouse "light weight deletes" were
not enabled or the required setting `allow_nondetermistic_mutations` was not enabled and the user did not have permission
to apply it. This condition is now detected on startup, and an exception will be thrown if `use_lw_deletes` is configured
in the profile. Otherwise, a warning will be logged that incremental models will be slower (because such models will
be downgraded to use the `legacy` incremental strategy). This should prevent the confusing behavior in
https://github.com/ClickHouse/dbt-clickhouse/issues/197 by throwing an early exception for an unsupported configuration.

Improvements
- Minimal compatibility with dbt 1.7.x. The date_spine macro and additional automated tests have not been implemented,
but are planned for a future patch release.
- DBT 1.7 introduces a (complex) optimization mechanism for retrieving a dbt catalog which is overkill for ClickHouse
(which has no separate schema/database level), so this release includes some internal catalog changes to simplify that process.
