Custom updater section in README.md is confusing

[eesprit]

Hi,

Looking at the README.md to see how to install this (fantastic) plugin, I discovered that the section about Custom Updater is outdated :

• the JSON file has been deleted from the repos more than a year ago
• Custom Updater repos indicates that it is deprecated

You should remove this section from the README.md because it is a little confusing for newbies like me ;)
