Add displayName "Hostinger" to the hostinger entry (#4014)

Partner-requested display label: the /plugin browse UI shows the entry
name (lowercase slug) unless displayName is set. Install slug stays
hostinger; no change on the plugin repo side. Same shape as the convex
entry here and the qodo relabel on -community. displayName is supported
since Claude Code v2.1.143 and falls back to name on older versions.
