Please make it possible to disable auto-update for a specific extension

[bmrejen]

Some of us are using extensions that we paid for once and whose licence have expired. For example, I can use Quokka 1.4.069 but any newer version than that won't work with my configuration.
It would be great to select specific extensions whose versions should skip auto-update.

Please try the feature Install Another Version... - right click on extension to see this action. Installing another version will lock the extension to that version.
