CI: test with Go 1.19 and Go 1.20

[sywhang]

Only Go 1.19 and Go 1.20 are supported after Go 1.20 has been released.

This makes CI only run against Go 1.19 and Go 1.20.

Need to update staticcheck

[sywhang]

huh, weird. Looks like staticcheck has a bug - it reports scope as not being used when it clearly is being used.

internal/digtest/container.go:49:6: type scope is unused (U1000)
