Add dfr to dataframe cmds (#7998)

# Description This PR tries to resolve the overloading issue by going back to our original naming convention for dataframes. So, this PR renames all dataframe commands with a prefix of `dfr`. Some commands like `open-df` were renamed to `dfr open` and things like `into df` were renamed `dfr into-df`. I'm sure we can optimize naming a bit, but it seems to compile now. # User-Facing Changes All dataframe commands are prefixed with dfr. # Tests + Formatting Don't forget to add tests that cover your changes. Make sure you've run and fixed any issues with these commands: - `cargo fmt --all -- --check` to check standard code formatting (`cargo fmt --all` applies these changes) - `cargo clippy --workspace -- -D warnings -D clippy::unwrap_used -A clippy::needless_collect` to check that you're using the standard code style - `cargo test --workspace` to check that all tests pass # After Submitting If your PR had any user-facing changes, update [the documentation](https://github.com/nushell/nushell.github.io) after the PR is merged, if necessary. This will help us keep the docs up to date.
