PER_5831: Update dependencies and selenium test

[pranavz28]

Changes performed in branch PER_5831

Summary:

• Updated JavaScript and Ruby dependencies to recent versions.
• Fixed tests to be compatible with newer selenium-webdriver API.
• Installed missing stdlib gems (webrick, base64) required for Ruby 3.4+.
• Ran two Percy web builds (builds captured below) to verify snapshots upload successfully.

Files changed:

• package.json — bumped todomvc-app-css to ^2.4.3 and @percy/cli to ^1.31.2
• Gemfile — bumped selenium-webdriver to ~> 4.36.0; added webrick and base64 gems
• tests/todo.rb — updated Selenium driver initialization to use options:
• README.md — added Versions section reflecting new versions used
• Gemfile.lock, package-lock.json — updated by package managers

Steps performed:

1. Ran web-t && make test to reproduce existing behavior and capture initial errors.
2. Inspected and updated npm and Ruby dependencies (package.json, Gemfile).
3. Ran npm install and bundle install / bundle update to install updated packages into node_modules and vendor/bundle.
4. Fixed missing stdlib dependency errors by adding webrick and base64 to Gemfile.
5. Updated tests/todo.rb to use Selenium::WebDriver.for(:firefox, options: options) to match selenium-webdriver 4.36.0 API.
6. Ran Percy web builds twice (below) to ensure snapshots were taken successfully.
7. Created branch PER_5831, committed changes, and pushed to origin.

Percy builds created during verification:

• Build 98: https://percy.io/9560f98d/web/test-pranav-8a4f5725/builds/43773647
• Build 99: https://percy.io/9560f98d/web/test-pranav-8a4f5725/builds/43773657

Notes / Rationale:

• percy-selenium latest available is 1.1.1; no upgrade needed there.
• Selenium API changed between 4.0.x and 4.36.x; the driver init argument name is now options:. Adjusted test accordingly.
• Adding webrick and base64 ensures compatibility with Ruby 3.4+ where these are no longer bundled by default.

How to reproduce locally:

1. Load Percy token with web-t in your shell (already present in this environment).
2. Run make install to set up node and Ruby dependencies.
3. Run make test to execute tests and create Percy snapshots.
