This reverts commit f0e93c2fa9 (PR #7417). I'm currently [working on improving cell paths](https://github.com/nushell/nushell/issues/7498#issuecomment-1356834798), and I realized that I would need to make several improvements to `into cellpath` along the lines of Jakub's comment here: https://github.com/nushell/nushell/pull/7417#issuecomment-1345264955 I don't think `into cellpath` is quite ready for prime-time, and I'd like to remove it before the upcoming release.
