Filter out undefined values in `INSERT` queries

[alii]

@cirospaciari This is still a problem for me in Bun 1.3.5. The following code:

const [record] = await sql`
	INSERT INTO "MyTable" ${sql({
		foo: undefined,
		id: Bun.randomUUIDv7()
	})}
`;

Results in this error:

null value in column \"foo\" of relation \"MyTable\" violates not-null constraint

Any chance your fix could also be ported over support INSERT statements?
