test/integration: reenable staticcheck and fix "Error checking" test

Staticcheck has been supporting go1.18 for a while,
so reenable the skipped test.

https://go-review.googlesource.com/c/vscode-go/+/405551 rearranged
how diagnostics collection was passed. We need to pass them as goCtx.

Updates #1950
Fixes #2282
