Plugins raise when passing `pl.lit(1)` without specifying dtype

Checks

[X] I have checked that this issue has not already been reported.
[X] I have confirmed this bug exists on the latest version of Polars.

Reproducible example

I've made a simple plugin, from the cookiecutter, with:

def add_one(expr: IntoExpr) -> pl.Expr:
    expr = parse_into_expr(expr)
    return register_plugin(
        args=[expr],
        symbol="add_one",
        is_elementwise=True,
        lib=lib,
    )

and

use polars::prelude::*;
use pyo3_polars::derive::polars_expr;

#[polars_expr(output_type=Int64)]
fn add_one(inputs: &[Series]) -> PolarsResult<Series> {
    let out = inputs[0].i64()?.apply_values(|x|x+1);
    Ok(out.into_series())
}

I then run

import polars as pl
from plugin_mcve import add_one

df = pl.DataFrame({
    'a': [1,2,3],
})
result = df.with_columns(a_plus_one = add_one('a'))
result = df.with_columns(a_plus_one = add_one(pl.lit(1)))
print(result)

Log output

Issue description

From git bisect, this is due to #15832. I just wanted to check if it's intentional - are users now required to always specify dtype when passing pl.lit to plugins?

Expected behavior

Either an informative message, or for it to work as before
