ISSUE-19454: Fixes broken looker lineage

[olof-nn]

Describe your changes:

Fixes 19454

Looker lineage is broken when a table reference is enclosed by backticks (common when using BigQuery).
This addresses that issue.

Type of change:

• Bug fix

Checklist:

• I have read the CONTRIBUTING document.
• My PR title is Fixes <issue-number>: <short explanation>
• I have commented on my code, particularly in hard-to-understand areas.
• For JSON Schema changes: I updated the migration scripts or explained why it is not needed.

• I have added a test that covers the exact scenario we are fixing. For complex issues, comment the issue number in the test for future reference.

I f i understand correctly this is so the query is compiled to the correct dialect, right?

[olof-nn]

The cleaning of the table name already occurs, this is just adding the functionality of making `project_id.dataset_id.table_id` -> project_id.dataset_id.table_id. This is common to enclose table references like this in BigQuery. Our looker views are defined like:
sql_table_name: `project_id.dataset_id.table_id` ;;. The Looker ingestion then tries to find lineage references by searching for:

db: `project_id
schema: dataset_id
table: table_id`

Thus we find no lineage between looker <-> BQ

This addition in the _clean_table_name method will address that

[olof-nn]

I.e. it is not compiling the query. That is happening only if the table ref is a derived table in Looker. That scenario is already handled in the elif statement
