Well, this question about "needs an update" or "outdated" addons was aswered like 1000000 times meanwhile here, at Google and other platforms, official ESO forums and so on...
Here is the info you hopefully were searching for from the AddOn Help/Support forums, and not able to find yourself

What you have to do:
Either spend ours by manipulating addon's txt files locally on your harddisk, like dakjaniels wrote (partially; he said "uplaod" but I guess you meant you do no want to uplaod an addon but update it as you are a user, not a dev), to make the inagme UI show you" All is updated", but othign really changed then except that txt entry that does not say anything about an addon's actual functionality.
Or: Ignore the ingame "not updated" warning and just play! Save your time and just use it as long as you get no error messages.
Ignore whatever ZOs decided to show there as "outdated" or "old" or "not updated" as it's nothing that tells you if addons work, or not.
If Minion shows an update: Update! This fixes or adds new features.
Read the changelog of addons before updating so you know what was changed (fixes/new features) and maybe skip that update if you do not nee any new features. But basically updating is always a good idea, if Minion provides an update. One never knows what the updates contains as fixes that were not mentioned in the changelog
