feat: add MONGOMS_DOWNLOAD_URL env variable for downloading binary from url

* refactor: 💡 download binary from the full address of mirror url

MONGOMS DOWNLOAD_MIRROR environment variable should be able to install
binaries from wherever users wants to .Without this refactor, this
variable is used just to allow user to install binaries from another
domain, but this is not considering the full path of binary

* fix: 🐛 add the new env variable MONGOMS DOWNLOAD_MIRROR

Add the new environment variable MONGOMS DOWNLOAD MIRROR to
getDownloadUrl method to don't break anybody apps
