templatekw: add {size} keyword as an example of fctx-based keyword I'll add {status}, and I think some lfs keywords can be migrated to this. I'm not certain how many fctx-based keywords will be introduced into the global space, but if there are a couple more, we'll probably need to sort them out to the "File Keywords" section in the templater help. Until then, fctx keywords are hidden as experimental.
