update to rust version 1.87.0 (#16437)

The PR upgrades nushell to rust version 1.87.0.

## Dev overview from clippy
- I added `result_large_err` to clippy in the root Cargo.toml to avoid
the warnings (and a few places in plugins). At some point a more proper
fix, perhaps boxing these, will need to be performed. This PR is to just
get us over the hump.
- I boxed a couple areas in some commands
- I changed `rdr.bytes()` to `BufReader::new(rdr).bytes()` in nu-json

## Release notes summary - What our users need to know
Users can use rust version 1.87.0 to compile nushell now
