update: component doc improvements
The idea of this MR is to change the imports from import {SolidTemplateElement} from 'https://unpkg.com/@startinblox/core@0.10';
to import SolidTemplateElement from 'https://unpkg.com/@startinblox/core@0.10/dist/solid-template-element.js';
to prevent conflicts between core versions.
The other modifications are basically just typos fixes
