Fix #61 (#62)

* Replace PDM to use `sync` instead of `install`

As suggested in the official docs:
<https://pdm.fming.dev/2.7/usage/advanced/#use-pdm-in-continuous-integration>

* Upgrade PDM

* Rewrite the CI/CD

Based on the:
<https://pdm.fming.dev/2.7/usage/advanced/#use-pdm-in-continuous-integration>

Notable changes include:
- Pin versions of each step.
- Explicitly define all options of `setup-pdm` action.
- Reimplement cache using built-in solution of `setup-pdm` action.
