fix: correct package name from solaris to polaris (#26)

* ci: add E2E preflight check for Headlamp connectivity and plugin version

Adds a diagnostic step before E2E tests that:
- Logs the expected plugin version from package.json
- Verifies Headlamp is reachable (fails fast if not)
- Attempts to list installed plugins for debugging

This surfaces version mismatches and connectivity issues immediately
instead of requiring analysis of cryptic test timeout failures.

* fix: correct package name from headlamp-solaris to headlamp-polaris

The package name was misspelled as "solaris" instead of "polaris" in
artifacthub-pkg.yml, package.json, and package-lock.json.

Fixes PRI-49

* fix: correct package name from headlamp-solaris to headlamp-polaris

Fixes the ArtifactHub package name typo introduced in 0.6.0.
Only changes the name field in artifacthub-pkg.yml, package.json,
and package-lock.json. No dependency or workflow changes.

Fixes #25
