fix: change module path to github.com/dolonet/mtg-multi
go install github.com/dolonet/mtg-multi@latest was broken because go.mod
declared module path as github.com/9seconds/mtg/v2 while the repo lives
at github.com/dolonet/mtg-multi. Users ended up installing upstream
binary without multi-secret support.

For a couple of releases we use collected IPs as a prioritized source

Thus, this PR flips priorities, so users could have auto-update enabled
as a source of secondary addresses, not primary ones
