fix(backend-native): move to post-installer ^0.1.2, dropping decompress

Released as 0.1.2 rather than 0.2.0, so the range is ^0.1.2. A caret on 0.1.x
spans >=0.1.2 <0.2.0 and can reach it — unlike the previous ^0.0.7, where the
caret on a 0.0.x version pinned exactly 0.0.7 and no float could escape
@cubejs-backend/shared@0.33.20.

Lockfile regenerated against the published version:

  decompress@^4.2.1            gone (only decompress-response, unrelated, remains)
  @cubejs-backend/shared@0.33.20  gone
  @cubejs-infra/post-installer    0.1.2

Net -152 lines. The new @octokit/* entries are expected: post-installer gained
github_artifact:// support via octokit in 0.1.0, which the old 0.0.7 pin predated.

Behaviour of the published artifact against this package's own resources config
is identical to 0.0.7 — exit 0, same constructed URL
native-<platform>-<arch>-<libc>-<libpython>.tar.gz.
