fix failed release: regenerate the *.mpack file

Set NVIM_API_PRERELEASE=true to regenerate the *.mpack file, because it
was generated from an old binary accidentally, which caused the release
to fail:

    test/functional\api\version_spec.lua:133: Expected objects to be the same.
    Passed in:
    (table: 0x0c6175a8) {

       *[1] = {

          [2] = '' } }
      [return_type] = 'Dictionary'
