[Snyk] Fix for 1 vulnerabilities

[Eric-Guo]

Snyk has created this PR to fix 1 vulnerabilities in the yarn dependencies of this project.

Snyk changed the following file(s):

• package.json

Note for zero-installs users

If you are using the Yarn feature zero-installs that was introduced in Yarn V2, note that this PR does not update the .yarn/cache/ directory meaning this code cannot be pulled and immediately developed on as one would expect for a zero-install project - you will need to run yarn to update the contents of the ./yarn/cache directory.
If you are not using zero-install you can ignore this as your flow should likely be unchanged.

⚠️ Warning

Failed to update the yarn.lock, please update manually before merging.

Vulnerabilities that will be fixed with an upgrade:

Regenerate lockfile after bumping webpack plugins

This commit updates compression-webpack-plugin and css-minimizer-webpack-plugin in package.json but does not update pnpm-lock.yaml, which still pins the old specs (^9.2.0 and ^4.2.2 at pnpm-lock.yaml:66-74). In this repo, CI installs JS deps with pnpm install --frozen-lockfile (.github/workflows/rubyonrails.yml:54), so the workflow will fail once package.json and lockfile diverge. Please regenerate and commit pnpm-lock.yaml with these dependency changes.

[Copilot]

These dependency bumps change package.json but the repo/CI uses pnpm install --frozen-lockfile, so leaving pnpm-lock.yaml unchanged will make installs fail and may prevent the vuln remediation from actually being applied. Please regenerate and commit pnpm-lock.yaml for these new versions (e.g., run pnpm install).

The PR description refers to "yarn dependencies" / updating yarn.lock, but this project declares packageManager: pnpm@... and uses pnpm-lock.yaml in CI. Consider adjusting the Snyk project/package manager settings or updating the PR text so it matches the actual tooling used here.
