[BUG]: drizzle-kit introspect generates CURRENT_TIMESTAMP without sql operator on date column

[kenn]

What version of drizzle-orm are you using?

0.33.0

What version of drizzle-kit are you using?

0.24.2

Describe the Bug

When I run drizzle-kit introspect, generated schema.ts is broken on the date type column because CURRENT_TIMESTAMP is not quoted with sql operator.

// broken
export const metrics = pgTable("metrics", {
	date: date("date").default(CURRENT_TIMESTAMP).notNull(),
})

// expected
export const metrics = pgTable("metrics", {
	date: date("date").default(sql`CURRENT_TIMESTAMP`).notNull(),
})

Only occurs on the date column, not on timestamp columns.

Expected behavior

Generate this instead:

sql`CURRENT_TIMESTAMP`

Environment & setup

Using pg v8.12.0
