Remove into bits after deprecation (#15039)

# Description
Follow up to https://github.com/nushell/nushell/pull/14634
# User-Facing Changes
`into bits` will be gone for good.

Use it under the new name `format bits`

## Note

Can be removed ahead of the `0.103.0` release as it was deprecated with
`0.102.0`
