ensure nightly builds always produce new packages

[jameslamb]

Contributes to rapidsai/build-planning#218

• uses the new patterns for versioning nightly packages (see builds: add support for computing a date-based version component at build time shared-workflows#603), to ensure they're always uploaded on new builds.

For conda:

# before
26.10.0a55[build=cuda12_260803_9da146ef]

# after
26.10.0a55[build=cuda12_260803200854_9da146ef]

For wheels:

unchanged. Unlike most other projects in this series, rapids-cli is using hatchling version for its nightly wheel versions and doesn't have scheduled nightly builds (only on new commits / tags), so doesn't face the same problems as most other RAPIDS projects with needing to upload new packages from an already-built commit:

Thank you for this @jameslamb.

Just to double check, this is to be consistent with the rest of the libraries correct? It doesn't seem to be necessary based on your PR description.

Yeah exactly, not too important for this project but makes it consistent with the rest of RAPIDS, which allows us to simplify some shared build stuff a bit: rapidsai/gha-tools#272
