Prevent cli release from mutating previously uploaded artifact (#2088)

Summary: Prevent cli release from mutating previously uploaded artifact

The v3 artifacts Action was deprecated and migrated from in #2079. The
new API has [breaking
changes](https://github.com/actions/upload-artifact/tree/main?tab=readme-ov-file#breaking-changes)
including that artifacts are now immutable. During #2079, I missed that
the cli release uploads to the same name twice (see grep below) and
caused the following [build
failure](https://github.com/pixie-io/pixie/actions/runs/12818680277/job/35745089942).

Relevant Issues: N/A

Type of change: /kind bugfix

Test Plan: Verified that the `macos-artifacts` artifact name is no
longer used multiple times
- [x] Double checked other actions to verify that they aren't trying to
mutate an artifact
