build(rust-compiler): retire the container image and the test cases

[petermetz]

1. This started off with me trying to fix the CVEs in the rust-compiler image.
2. I was able to get rid of most of them by changing the base image to ubuntu-24.04
3. The remaining high and critical ones were due to wasm-pack so went to see
   if we could upgrade that but we are already on the latest which is 8 months old.
   The vulnerabilities were reported on the wasm-pack repo 6 months ago along with
   a pull request that fixes them, neither the issue nor the pull request fixing it
   received any attention from the wasm-pack maintainers which lead me to believe
   that it is a liability to depend on it right now and we should instead look into
   a different tooling where the maintenance happens to have a little more resources
   dedicated to it. Java/Kotlin might be the way to go.
4. I've also looked into possible alternatives to wasm-pack but the only
   other tool I found that does the same thing is cargo-web which hasn't had
   a new release for 4 years and counting and has even more CVEs plaguing it
   than wasm-pack.
5. The official web assembly site links to wasm-pack when it comes to
   compiling to it from Rust so there's probably not a better maintained tool
   out there, but if someone finds something I'd love to start using it.
   In the meantime I'll just archive/retire/delete the rust compiler image
   and the tests associated with it because it's a maintenance burden that
   we don't need to carry.

Pull Request Requirements

• Rebased onto upstream/main branch and squashed into single commit to help maintainers review it more efficient and to avoid spaghetti git commit graphs that obfuscate which commit did exactly what change, when and, why.
• Have git sign off at the end of commit message to avoid being marked red. You can add -s flag when using git commit command. You may refer to this link for more information.
• Follow the Commit Linting specification. You may refer to this link for more information.

Character Limit

• Pull Request Title and Commit Subject must not exceed 72 characters (including spaces and special characters).
• Commit Message per line must not exceed 80 characters (including spaces and special characters).
