fix(package): dispatch get_links_for_type on Link::TYPE_* values

PHP resolves a link kind through `$package->{'get'.ucfirst($linkType)}()`,
so the argument is a `Link::$TYPES` value ("requires", "devRequires", ...).
The helper matched the composer.json key names ("require", "require-dev",
...) instead, so every caller passing a `Link::TYPE_*` constant got an empty
map back: `show <package>` printed none of its requires/provides/conflicts/
replaces sections, and `--format=json` carried none of those keys.

The two callers that were passing composer.json keys now pass the matching
`method`, as PHP does.
