docs: remove outdated group naming note

Allow jump host definitions to include an explicit port in the form user@host:port.
Default to port 22 when no port is provided and update the sample config and docs accordingly.

 ## Notes
 
 - `jump_host` values are resolved by name from `global.yaml`.
+- Jump hosts support `user@host` and `user@host:port`; if the port is omitted, `22` is used.
 - If a host does not define a user or port, global defaults are used.
 - `default_options` is present in the config but not consumed by the current script.
 - The sample config includes `ssh_options` in one file, but the current script does not consume it yet.
+- Sample host examples are stored as `sample-config/hosts/01_prod.yaml`, `02_staging.yaml`, and `03_dev.yaml`.
+- The `group` key is required for each host config file; the file name is only an internal storage detail.
 - When `-k` is used, entries from `known_hosts` are shown with the selected user or `root` by default.
 - `known_hosts` entries use port `22`.
 - The script uses strict Bash mode (`set -euo pipefail`).
