[CI] Cache .crates2.json and .crates.toml

[yutannihilation]

This pull request should fix this error. (Clearing cache might be needed)

error: binary `wasm-pack` already exists in destination
Add --force to overwrite
Error: Process completed with exit code 101.

It seems cargo install uses specific files to store information about the installed crates. This seems the same issue:

The answer suggests to cache ~/.cargo/.crates.toml and ~/.cargo/.crates2.json. According to Cargo's document, these two files are used by cargo install. I'm not sure if both files are needed, but caching this just worked fine.

.crates.toml, .crates2.json These hidden files contain package information of crates installed via cargo install. Do NOT edit by hand!

Thanks, I added or command chain(which wasm-pack || cargo install wasm-pack), suggested at the thread at main branch a47e6df , which isn't merged back to dev.
The build succeeds with that workaround but I'll merge this because it looks more consistent

Oh, I didn't notice the commit. Either should be fine!
