test: Update test expectations for metadata file in build uploads

Update the test mock and expected chunk data to reflect the addition
of `.sentry-cli-metadata.txt` to build upload archives.

The chunk hash changed from 18e40e6e932d0b622d631e887be454cc2003dbb5
to 985f82b2ff9f3749f9d4c71ecb02e0396b9bc5a3 due to the new metadata
file being included in the ZIP.
