B-21228

Summary

• Upgrade node and pdfjs-dist.
• Adjust babel and jest for transpiling ESM modules into CJS.
• Miscellaneous changes due to transpiling adjustments (Fileviewer export syntax, add exports script to index.html, cheerio resolution, etc.)
• Addition of Playwright to simulate real browser environment
  • Jest was upgraded in an attempt to be able to use a real pdfjs import rather than a mock, but this did not work as it is still experimental within Jest.
  • Persisting the Jest upgrade for better future support.
• Added polyfills for future support of handling within the webpack bundle. This effort was halted due to discovery of mymove already handling polyfills.
  • Package upgrades persisted for future support.
• Workaround of https://github.com/transcom/mymove/security/dependabot/146 has been removed due to it being OBE by the pdfjs-dist upgrade.
• Upgraded three library and .eslintrc to provide current linter support.
• Added error catching.
• Adjusted dev webpack config to use chunks, this facilitates transpiling dependencies separately. This provided many benefits for use within the BundleAnalyzerPlugin.
