feat: augments the list of cache-aware action in cache-audit

[ubiratansoares]

Another follow-up for #334.

Extends the list of known cache-aware Actions with the following

• https://github.com/mlugg/setup-zig
• https://github.com/oven-sh/setup-bun
• https://github.com/graalvm/setup-graalvm
• https://github.com/gradle/actions/blob/main/setup-gradle
• https://github.com/DeterminateSystems/magic-nix-cache-action
• https://github.com/docker/setup-buildx-action
• https://github.com/actions-rust-lang/setup-rust-toolchain
• https://github.com/nix-community/cache-nix-action

I did a search in both Github Marketplace and dependends of actions/toolkit/cache and filtered some of the most popular ones.

Thanks @ubiratansoares, nice work! I'm working on a small refactor for these models in #347 but I'll merge this first and then deconflict my draft.
