What Happened

When running sqlfluff on the following alter statement:
ALTER TABLE tsADD COLUMNmodified_at timestamp NULL DEFAULT NULL ON UPDATE CURRENT_TIMESTAMP;
I get the following error:
Found unparsable section: 'ON UPDATE CURRENT_TIMESTAMP'

Expected Behaviour

Parser should correctly parse the statement.

Observed Behaviour

Parsing fails.

How to reproduce

Run:
sqlfluff lint -d mysql update.sql
Where update.sql contains:
ALTER TABLE tsADD COLUMNmodified_at timestamp NULL DEFAULT NULL ON UPDATE CURRENT_TIMESTAMP;

Dialect
