Problem

Links to supporting documentation of HA Action node produces a 404 error.

Expected behavior

Actual behavior

Steps to reproduce

1. Open Node Red.
2. Open 'Help' for HA Action node.
3. From the 'Help' window, select and click on a link pointing to "Mustache Template"

Proposed changes

Links in the documentation points to https://zachowj.github.io/node-red-contrib-home-assistant-websocket../guide/mustache-templates.html.
They should point to https://zachowj.github.io/node-red-contrib-home-assistant-websocket/guide/mustache-templates.html
There's a formatting error in the link. Note the absence of two periods after the word websocket in the latter link.
