Migrate AirTable API to use PAT instead of API Key

[LimesKey]

I get INVALID_API_VERSION when trying to fetch records from Airtable using a personal access token, I assume this is because the program was never migrated to support PAT.

async fn get_airtable_records() -> Vec<Record<OnBoardRecord>> {
    let airtable = Airtable::new_from_env();
    // Get the current records from a table.
    let mut records: Vec<Record<OnBoardRecord>> = airtable
        .list_records(
            "Submissions",
            "Pending",
            vec!["OTP"],
        )
        .await
        .unwrap();

    // Iterate over the records.
    for (i, record) in records.clone().iter().enumerate() {
        println!("{} - {:?}", i, record);
    }
    return records;
}
