Fix the implied collect type to 'any' (#9827)

# Description

Previously, we had a bug slip in about implied collection caused by
`$in`, that this output type would be of type `string`.

The type system fixes in 0.83 now make this more visible and cause
issues. This PR changes the output of the implied collection to `any`.
At some point in the future, we may want to carry the type through where
we can, but `any` should unblock using `$in`.

fixes #9825

clippy::needless_collect -A clippy::result_large_err` to check that
you're using the standard code style
- `cargo test --workspace` to check that all tests pass
- `cargo run -- -c "use std testing; testing run-tests --path
crates/nu-std"` to run the tests for the standard library
