[Enhancement] Use actions/cache

[vaguecoder]

Is your enhancement request related to a problem on existing feature? Please describe.

Yes. The first GitHub action that I just added using #18 needs some caching of dependency installation.

Describe the solution you'd like

Use actions/cache which already available with GitHub actions. A bit of exploration is required.

Describe alternatives you've considered

Not sure.

Additional context

rs/zerolog makes use of the actions/cache. Need to check if using it as is will do us any good or if there are better usable ways.
