Change the default value for `auto-reload-config` to `true`

## Description Currently, the default value for `auto-reload-config` is `false` because the current implementation doesn't allow to support the current flow: 1. The user just installs AeroSpace and doesn't yet have a custom config 2. AeroSpace starts watching for `/Applications/AeroSpace.app/Contents/Resources/default-config.toml` 3. User creates the custom config. Expected: AeroSpace starts watching for the custom config instead of the built-in one. Unfortunately, it's unclear how to support the mentioned flow by using the current implementation of file watcher. The current implementation relies on file descriptors (file descriptors for non existing files don't exist) ## Motivation `auto-reload-config = true` is a sane default for new users. For old users, it just doesn't matter ## Possible solutions 1. Migrate to path watching API instead of file descriptor API https://github.com/nikitabobko/AeroSpace/pull/1743 2. Watch for descriptors of chain of containing directories? Could be very busy since we might need to watch for `$HOME`. ## References - previous issue: https://github.com/nikitabobko/AeroSpace/issues/163 - Original unmerged path watcher PR: https://github.com/nikitabobko/AeroSpace/pull/1743 - File descriptor PR: https://github.com/nikitabobko/AeroSpace/pull/1858
