Snowflake's SHOW EXTERNAL VOLUMES did not parse:

SHOW EXTERNAL VOLUMES LIKE 'my_%';

This adds a ShowExternalVolumes statement to the Snowflake dialect, reusing the existing ShowStatementFilter for the optional LIKE clause. All statements round-trip.

See the Snowflake SHOW EXTERNAL VOLUMES docs.

Split out of #2397 per review feedback, alongside the CREATE/DROP (#2475), ALTER (#2474), and DESC (#2472) PRs.

Rebased on latest main. @iffyio @LucaCappelletti94 could you take a look when you have a moment? (One of the PRs split out of #2397.)

At this time we are rather overworked review wise, so I'll get to it when I'll get to it. I would appreciate if you could help out with reviewing other PRs, as it would accelerate our work and ultimately speed up the PR queue.
