Subject: [PATCH 1/4] GitHub Actions: Fix hendrikmuhs/ccache miss on Build
 Jupyter Kernel

The GitHub Action [`hendrikmuhs/ccache-action`](https://github.com/hendrikmuhs/ccache-action) is used 8 times and most jobs successfully use that cache.  However, 2 jobs raise cache miss warnings at the bottom right of
https://github.com/lcompilers/lpython/actions/runs/9861518999
```
Save cache using key "sccache-build_jupyter_kernel--2024-07-11T04:38:05.880Z".
Warning: Saving cache failed: Error: Path Validation Error: Path(s) specified in the action for caching do(es) not exist, hence no cache is being saved.
```
This pull request attempts to fix the cache miss on the `Build Jupyter Kernel` job.

@hendrikmuhs Your review, please.
