fix: rename package.json name to headlamp-tns-csi-plugin (PRI-1444)

Package name was "tns-csi" but archive directory and ArtifactHub name
were both "headlamp-tns-csi-plugin", causing plugin installation to fail.
Also updated artifacthub-pkg.yml version to 1.0.1 and release URLs
to point to the new v1.0.1 release.
