refactor!(server/pipeline): raise UndefinedVariableError when variables are missing during rendering [TCTC-10013]

[Fanaen]

When there is a pipeline with a variable and a value is not provided, we get this error:

E       pydantic_core._pydantic_core.ValidationError: 3 validation errors for FilterStep
E       condition.ConditionComboAnd.and
E         Field required [type=missing, input_value={'column': 'price', 'operator': 'lt'}, input_type=dict]

E       condition.ConditionComboOr.or
E         Field required [type=missing, input_value={'column': 'price', 'operator': 'lt'}, input_type=dict]

This PR uses an already there param in toucan-connectors::nosql_apply_parameters_to_query to get UndefinedVariableError instead.

This PR adds nosql_apply_parameters_to_query in weaverbird.utils.toucan_connectors to use this param everywhere, and a test to match.

Thanks! Could you please also add an entry to the changelog ?

Also, the PR title isn't very explicit to me, how about something like "refactor!(server/pipeline): raise UndefinedVariableError when variables are missing during rendering"

Thanks for the review !
Would these changelogs be adequate: 01bc2ce?
