duckdb dialect

[eitsupi]

While working on updating prqlr, I noticed that duckdb dialect has been implemented. (Fantastic exclude support!)
However, this is not in the list of dialects available in prql-js and does not seem to be mentioned in the book.

prql/prql-js/src/lib.rs

Lines 110 to 119 in ad543b8

	Dialect::Ansi => D::Ansi,
	Dialect::BigQuery => D::BigQuery,
	Dialect::ClickHouse => D::ClickHouse,
	Dialect::Generic => D::Generic,
	Dialect::Hive => D::Hive,
	Dialect::MsSql => D::MsSql,
	Dialect::MySql => D::MySql,
	Dialect::PostgreSql => D::PostgreSql,
	Dialect::SQLite => D::SQLite,
	Dialect::Snowflake => D::Snowflake,

	- `sql.ansi`
	- `sql.bigquery`
	- `sql.clickhouse`
	- `sql.generic`
	- `sql.hive`
	- `sql.mssql`
	- `sql.mysql`
	- `sql.postgres`
	- `sql.sqlite`
	- `sql.snowflake`

From what I have played with R this seems to work well, but I was wondering if it is likely that that is not being intentionally listed.

Thanks for the question @eitsupi . We should update that. Feel free to transfer this to an issue to track that.

Contributions welcome, would be a reasonable first PR for anyone who wanted to get involved.
