fix: write sql migration files for wrappers

[samrose]

What kind of change does this PR introduce?

we need to produce a series of migration files on pkg build, although they are all a copy of the latest

The goal is to emulate what happened in the release gh action for https://github.com/supabase/wrappers

We need to fetch the release tags from github (in this case in a preBuild phase before we start building) write to file, and use the file to copy the latest wrappers--$current_version.sql to a wrappers--$prev_version-$current_version.sql and writing that into the nix store.

The outcome should be that all of those identical files end up at

/nix/store/postressqlbundle-hash/share/postgresql/extension/
