address golang ci modfile discovery (#967)

## Description

Github cache imposes a 10gb limit, after which cache entries
will automatically get evictions (LRU policy).  Various recent
queries have pinned our current cache size at 14-19 gb.  The
golangci-lint cache alone accounts for 5-9 gb of that usage.
Meanwhile, it takes a shorter time for that package to download
missing modules than it does to run our tests.  This change shuts
down the golangci cache in hopes that it improves our branch
caching retention.
