[Data Checks Bug]: Checks are not being picked up correctly with a space between # and check type

[kik-kik]

What is the issue?

Checks are not being picked up correctly with a space between # and check type.

For example: https://github.com/mozilla/bigquery-etl/blob/1b9750cdfbbc957b7580d83cd48714c19be4c767/sql_generators/glean_usage/templates/baseline_clients_last_seen_v1.checks.sql

What we see in the definition:

# warn
[..]
check_definition
[...]

Expected format:

#warn
[..]
check_definition
[...]

How can we reproduce the bug

This should even be addressed by having a validation process for the checks to ensure valid tags / labels are used for ETL checks.

Or, by also supporting tags / labels that contain a space between # and the ETL check mode (fail / warn)
