Use commit hash (not tag) for `EnricoMi/publish-unit-test-result-acti…

…on` version specification (#530)

Currently we are referencing a tag when specifying the version of the
`EnricoMi/publish-unit-test-result-action`, which is potentially
mutable.

[It was
requested](https://github.com/hazelcast/hazelcast-mono/pull/2422/files/e0b1647cd0e713602c2fe215bf253510637d8037#r1727207988)
that the commit SHA be used instead, as per the [GitHub actions security
hardening
guide](https://docs.github.com/en/actions/security-for-github-actions/security-guides/security-hardening-for-github-actions#using-third-party-actions).

Updated the version specification to the commit hash of the [currently
used
version](https://github.com/EnricoMi/publish-unit-test-result-action/releases/tag/v2.17.0)
- i.e. no changes to the actual version of the action being used.
