fix(diesel_cli): use separate lines for multiple annotations

[DannyGoldberg]

We were running into a compilation error from diesel-derives where we had both a sql_name and max_length annotation for the same property, which would generate something like this:

diesel::table! {
    example (id) {
        id -> Uuid,
        #[sql_name = "type", max_length = 200]
        type_ -> Nullable<Varchar>,
    }
}

and would throw a compilation error like this:

error: Invalid `table!` syntax. Please see the `table!` macro docs for more info.
       Docs available at: `https://docs.diesel.rs/master/diesel/macro.table.html`

note: this isn't yet tested locally, as I've had trouble getting this repo running locally

This should result in something like the following, which wouldn't fail to compile:

diesel::table! {
    example (id) {
        id -> Uuid,
        #[sql_name = "type"]
        #[max_length = 200]
        type_ -> Nullable<Varchar>,
    }
}

@Ten0 this intends to fix an issue I ran into from #3552, where multiple comma-separated annotations would cause compilation errors -- github actions tests pass, although I am having some trouble testing it locally

Thanks for opening this PR. Can you add a test for that in diesel_cli/tests/print_schema.rs (see the print_schema dir there for examples of existing test cases.)
