document config option "url_fetch_method" (#24638)

- Change config from the undocumented `use_curl: true/false` to `url_fetch_method: urllib/curl`.
- Documentation of `url_fetch_method` in `defaults/config.yaml`
- Default fetch option explicitly set to `urllib` for users who may not have curl on their system

To upgrade from `use_curl` to `url_fetch_method`, run `spack config update config`
