Ignore invalid jars inside of the updates folder (Fixes #7751)
This really needs a deeper look here, the way updates are handled is
fairly immature, but, this wasn't ever intended to be a large scale thing

Ideally, imho, we'd collect the list of update files into some form of Map,
that way we just have a reference of Name > File refs, and can filter out
cases where there are two versions of a plugin in there and warn expectidely,
but, that creates some complications, you would need to fall back to a dir
scan in the case of a plugin calling loadPlugin, but, it would at least
give us more defined behavior, as well as improve performance here vs
repeatidely trying to deserialise the plugin.yml defs for every file
in there on every load
