Add caching

[dudicoco]

Rather than downloading all binaries on every run it would be more efficient and faster if the action would cache the aqua binary and all of the packages binaries.

aqua-installer doesn't support caching, but you can cache binaries using actions/cache.

e.g.

- uses: actions/cache@v3.3.1
  with:
    path: ~/.local/share/aquaproj-aqua
    key: v1-aqua-installer-${{runner.os}}-${{runner.arch}}-${{hashFiles('aqua.yaml')}}
    restore-keys: |
      v1-aqua-installer-${{runner.os}}-${{runner.arch}}-
- uses: aquaproj/aqua-installer@v2.1.1
  with:
    aqua_version: v2.6.0

Please fix parameters properly.

e.g.

- uses: actions/cache@v3.3.1
  with:
    path: ~/.local/share/aquaproj-aqua
    key: v1-aqua-installer-${{runner.os}}-${{runner.arch}}-${{hashFiles('.aqua/*.yaml')}} # Change key
    restore-keys: |
      v1-aqua-installer-${{runner.os}}-${{runner.arch}}-

It's a bit difficult to run actions/cache in aqua-installer because it is a bit difficult to decide parameters.

Note that by default aqua-installer runs aqua with -l option so packages that aren't run in the workflow aren't cached.
If you want to cache all packages, please set aqua_opts to unset -l option.

- uses: aquaproj/aqua-installer@v2.1.1
  with:
    aqua_version: v2.6.0
    aqua_opts: "" # Unset `-l` option

But note that if -l isn't set, aqua installs packages that aren't run in the workflow uselessly.

So caching of aqua-installer is more complicated than you expect.

I updated the document.

Thanks @suzuki-shunsuke.

Perhaps the action could just cache the aqua binary by default then? The parameters for that could be static.
