reword documentation on nix-store --import

Browse Source 
- add links to definitions of terms
- one sentence per line
- be more specific about which store is used for the import
- clearly distinguish store paths and store objects
- make a recommendation to use `nix-copy-closure` for efficient SSH transfers

# Description
The operation `--import` reads a serialisation of a set of store paths
produced by `nix-store --export` from standard input and adds those
store paths to the Nix store. Paths that already exist in the Nix store
are ignored. If a path refers to another path that doesn’t exist in the
Nix store, the import fails.
The operation `--import` reads a serialisation of a set of [store objects](@docroot@/glossary.md#gloss-store-object) produced by [`nix-store --export`](./export.md) from standard input, and adds those store objects to the specified [Nix store](@docroot@/store/index.md).
Paths that already exist in the target Nix store are ignored.
If a path [refers](@docroot@/glossary.md#gloss-reference) to another path that doesn’t exist in the target Nix store, the import fails.
> **Note**
>
> For efficient transfer of closures to remote machines over SSH, use [`nix-copy-closure`](@docroot@/command-ref/nix-copy-closure.md).
