SQL code highlighting is broken

[mtoy-googly-moogly]

Once upon a time, I think, we highlighted SQL Inside of Malloy properly. Something like:

source: MOCK_DATES is duckdb.sql(
"""SELECT
  ts::DATE as MOCK_DATE_COLUMN
  FROM generate_series(
    TIMESTAMP '2000-01-01',
    TIMESTAMP '2030-01-01',
    INTERVAL '1' DAY) AS t(ts)
""")

There are two problems.

1. Someone (I suspect me) broke this.
2. There was no test to stop me from breaking this.

It's a little finicky -

source: MOCK_DATES is duckdb.sql("""
SELECT
  ts::DATE as MOCK_DATE_COLUMN
  FROM generate_series(
    TIMESTAMP '2000-01-01',
    TIMESTAMP '2030-01-01',
    INTERVAL '1' DAY) AS t(ts)
""")

works. So we're just missing a like \s* somewhere
