[FEATURE]: Allow passing empty arrays to `.values()` during insert

### Describe what you want

When inserting values into the database, sometimes I end up needing to add an empty array. Currently this throws an error:
```
Error: values() must be called with at least one value
at PgInsertBuilder.values (/Users/hansenq/Documents/CS/lightski/node_modules/src/pg-core/query-builders/insert.ts:50:10)

```

Supporting `[]` inside `db.insert(myTable).values([])` would be more ergonomically friendly and allow me to skip pulling the array into a variable and checking the length of that array before calling `db.insert`.

This is similar in spirit to #1295. Edit: Looks like this is the same as a previous issue https://github.com/drizzle-team/drizzle-orm/issues/1078
