♻️ Match --ide-hover with help command (#11284)

# Description
Hi! @fdncred pointed that the `help` command doesn't give the same
result as hovering a command in the VS Code extension. I digged out that
this trace back from `src/ide.rs`, so I decided to change this: (look at
the window of VS Code when hovering help)

# User-Facing Changes
The `--ide-hover` change a lot, by matching the `help` command of the
terminal nushell

The only missing part is the `subcommands` part

# Tests + Formatting
All good!
