www-servers/caddy: add 2.8.0_beta2, guide on deps tar creation

Changes:
* Support versions including beta
* Instead of `mv`ing vendor dir do symlink.
* use aesterisks instead of hardcoding dir name at various
places (dist dir)

Instructions for creating deps tarball:
1. git init, git add ./
2. `go get` ALL the modules
3. import ALL modules in cmd/caddy/main.go
4. git diff > go-mod-sum.patch
5. go mod vendor -v
6. tar -c vendor/ go-mod-sum.patch
