feat: adds rover install --plugin supergraph-{0,2} (#1058)

fixes #1046. 

this PR adds `rover install --plugin supergraph-{0,2}` and removes `rover-fed2`.

the curl and npm installers will both run `rover install --plugin supergraph@latest-0` and `rover install --plugin supergraph@latest-2`. you can run `rover install --plugin supergraph@v2.0.0` to get an exact version.

`rover supergraph compose` will check if a new supergraph binary has been released and download that to use it for composition if it is available. these network checks can be skipped with `--skip-update` in order to use the plugins that were installed at the same time as rover. you can also specify `federation_version: =2.0.0` in `supergraph.yaml` to get an exact version that will only download the plugin once and won't check for updates unless the number changes.

the npm installer now puts rover in `~/node_modules/.bin` instead of `~/node_modules/binary-install/bin`, and sets `APOLLO_NODE_MODULES_BIN_DIR` so that rover knows where it lives and can install the supergraph binaries there as well.
