Updated subpackage names to match the most recent format (#33199)

Updated the subpackage names to use the format
`${{package.name}}-subpackagename`.

Fixes: chainguard-dev/internal-dev#5147

#### For new version streams
<!-- remove if unrelated -->
- [x] The upstream project actually supports multiple concurrent
versions.
- [x] Any subpackages include the version string in their package name
(e.g. `name: ${{package.name}}-compat`)
- [x] The package (and subpackages) `provides:` logical unversioned
forms of the package (e.g. `nodejs`, `nodejs-lts`)
- [ ] If non-streamed package names no longer built, open PR to withdraw
them (see [WITHDRAWING
PACKAGES](https://github.com/wolfi-dev/os/blob/main/WITHDRAWING_PACKAGES.md))
