Unique cache-key for job matrix objects (#88)
* Unique cache-key for job matrix objects * Update workflow to use object in job matrix * Restore key should always match startswith * fixup! Unique cache-key for job matrix objects * Debug no-matrix * Tests require overriding workflow/job * Skip generating matrix_key when no matrix is used * Install jq for self-hosted runners * fixup! Install jq for self-hosted runners * Skip install when not needed * fixup! Skip install when not needed * fixup! Skip install when not needed * Improve `cache-name` description Co-authored-by: Ian Butterworth <i.r.butterworth@gmail.com> * Update description in README * Use actions/checkout@v4 in example * add missing period --------- Co-authored-by: Ian Butterworth <i.r.butterworth@gmail.com>

### Optional Inputs
|

|
||||
- `cache-name` - The cache key prefix. Defaults to `julia-cache-${{ github.workflow }}-${{ github.job }}`. The key body automatically includes matrix vars and the OS. Include any other parameters/details in this prefix to ensure one unique cache key per concurrent job type.
|

- `cache-name` - The cache key prefix. Defaults to `julia-cache;workflow=${{ github.workflow }};job=${{ github.job }}`. The key body automatically includes the OS and, unless disabled with `include-matrix`, the matrix vars. Include any other parameters/details in this prefix to ensure one unique cache key per concurrent job type.
|
||||
- `include-matrix` - Whether to include the matrix values when constructing the cache key. Defaults to `true`.
|
||||
- `depot` - Path to a Julia [depot](https://pkgdocs.julialang.org/v1/glossary/) directory where cached data will be saved to and restored from. Defaults to the first depot in [`JULIA_DEPOT_PATH`](https://docs.julialang.org/en/v1/manual/environment-variables/#JULIA_DEPOT_PATH) if specified. Otherwise, defaults to `~/.julia`.
|
||||
- `cache-artifacts` - Whether to cache the depot's `artifacts` directory. Defaults to `true`.
