fix(clickhouse): drop a comment that broke webhook_deliveries_v1 migration parsing

The 034 migration had an inline comment containing a semicolon. The test
ClickHouse migration runner splits statements on semicolons, so it cut the
CREATE TABLE mid-statement and tried to parse the comment tail as SQL, which
failed ClickHouse setup for every test suite that starts a container. Removing
the comment leaves the CREATE as a single statement.
