feat: add --installation-key flag to package version displaydependencies @W-20525733@

[WillieRuemmele]

Summary

• Add --installation-key (-k) flag to sf package version displaydependencies so users can query dependencies of key-protected subscriber package versions
• Requires feat: support installation key for dependency graph queries @W-20525733@ forcedotcom/packaging#886 (adds installationKey threading in the library)

Fixes forcedotcom/cli#3469

Work Item

@W-20525733@: Package Version Display Dependencies not possible, if installation key required

Proof of Work

• Tests: 115 passing (no regressions)
• Lint: clean (on changed file; repo-wide header/header issue is pre-existing)
• Type check: clean
• Snapshot: updated and passing

Test plan

• Run sf package version displaydependencies -p 04t<key-protected> -k <key> -v <hub> — should display the dependency graph
• Run sf package version displaydependencies -p 04t<non-protected> (no key) — should still work as before
• Run sf package version displaydependencies -p 08c... — unaffected path, should work as before

Proof

../../oss/plugin-packaging/bin/run.js  package version displaydependencies --package 04tKa000002wLaqIAE --installation-key testKey123
strict digraph G {
         node_04tKa000002wLaqIAE [label="KeyProtectedTestPkg@0.1.0.1"]
         node_04tKa000002GlS0IAK [label="dancingbears-8e43a10e7d783c95@1.0.0.1"]
         node_04tKa000002wLaqIAE -> node_04tKa000002GlS0IAK
}

QA notes:
Using dreamhouse-lwc with scratch org:

✅ (Protected 04t + key): Shows dependency graph, use -k / --installation-key

✅ (Protected 04t, no key): throw an error Error (1): Please provide installationkey when querying against SubscriberPackageVersion that is protected by installationkey
✅ (Non-protected 04t): Shows dependency graph
✅ (Pkg 08c): Shows dependency graph
