[Core] The schemas context variable has its own page but database_schemas does not

[dbeatty10]

Link to the page(s) on docs.getdbt.com requiring updates

This page has sections for schemas and database_schemas:
https://docs.getdbt.com/reference/dbt-jinja-functions/on-run-end-context

This page for schemas also exists:
https://docs.getdbt.com/reference/dbt-jinja-functions/schemas

But this page does not exist for database_schemas:
https://docs.getdbt.com/reference/dbt-jinja-functions/database_schemas

Tell us more about this update

So to resolve this discrepancy, it seems like either both should have their own page or neither should have their own page.

Although not directly related, I noticed this discrepancy when looking at dbt-labs/dbt-core#9600 (comment) and was researching a context variable that contains the command-line args (which ended up being invocation_args_dict).
