Change the ignore command to use drain() instead of collecting a value (#12120) # Description Change the `ignore` command to use `drain()` instead of collecting a value. This saves memory usage when piping a lot of output to `ignore`. There's no reason to keep the output in memory if it's going to be discarded anyway. # User-Facing Changes Probably none # Tests + Formatting - :green_circle: `toolkit fmt` - :green_circle: `toolkit clippy` - :green_circle: `toolkit test` - :green_circle: `toolkit test stdlib` 2024-03-08 07:18:26 +00:00			`use nu_test_support::nu;`
