Subject: [PATCH] test(void): run PGlite initdb once for the wrapper migration
 tests

Each new PGlite runs initdb. On Linux CI that took most of the 5s test
deadline, and the pg bundle test timed out at 5108ms. Run initdb once in a
hook with its own budget, and load each test's fresh database from the
saved data directory.
