Review Comment:
I'm thinking we can link to
[snowflake](https://docs.snowflake.com/en/sql-reference/operators-subquery#all-any)
instead? Since that's a supported dialect that has the subquery functionality.
The current link doesnt seem to refer to any specific dialect so it could add
confusion later on when trying to figure what features in the parser to maintain

Ah cool! Can we include the link in the comment here as well? It could help
later on in case someone comes across this and wonders the same
