Select stable

[qknight]

This is the select_stable example I wrote which is referenced https://github.com/leptos-rs/leptos/issues/1937.

I fixed to snake_case but the issue with adding an item while the first item is selected still persists.

I compiled this on NixOS linux with rustc 1.73.0 (cc66ad468 2023-10-03)

The javascript console on windows prints:

panicked at /mnt/c/Users/joschie/Desktop/Projects/leptos/leptos_reactive/src/signal.rs:1595:21:
already mutably borrowed: BorrowError
