Upgrade pdf.js to 3.11.174

What does this MR do and why?

Upgrade pdf.js version to 3.11.174. This change adds two babel plugins to parse javascript syntax that are supported by webpack 4

• @babel/plugin-transform-optional-chaining
• @babel/plugin-transform-logical-assignment-operators Both were introduced in v3.0.279

🗒 This is Part 1 of the 2 MRs that eventually allows us to safely remove the patch that prevented PDF.js from evaluating scripts when rendering PDF files in the UI to close a security vulnerability but had performance implications around rendering fonts.
