Allow clippy::pedantic for star import

[DannyGoldberg]

To fix:

warning: usage of wildcard import
   --> src/models/schema_gen.rs:174:9
    |
174 |     use diesel::sql_types::*;
    |         ^^^^^^^^^^^^^^^^^^^^ help: try: `diesel::sql_types::{Nullable, Text, Timestamptz, Uuid, Varchar}`
    |
    = help: for further information visit https://rust-lang.github.io/rust-clippy/master/index.html#wildcard_imports

For now, I added a patch_file to my diesel.toml configuration, but I figured it'd be nicer for all if it's added automatically.

Or perhaps there's a better way that a reviewer will recommend :)

EDIT: I was able to find a fix without a patch file:

-#[allow(clippy::all)]
+#[allow(clippy::all, clippy::pedantic)]
 pub mod schema_gen;

So a patch_file is no longer necessary for my needs, although leaving this up in case it's useful for others

it seems like there's an unrelated clippy failure in diesel_derives/src/sql_function.rs:224:22: https://github.com/diesel-rs/diesel/actions/runs/6422538158/job/17439224135?pr=3816#step:8:78

Thanks for opening this PR.

Rather than adding this #[allow()] to each generated instance of the table! macro, I would go and allow it here:

diesel/diesel_derives/src/table.rs

Line 184 in 0377c25

#[allow(unused_imports, dead_code, unreachable_pub)]

instead (so in the macro itself)
