Protobufjs CLI compilation is broken with bad version of marked npm package

[utsavkapoor]

protobuf.js version: 6.8.3

Protobufjs CLI compilation is broken due a version bump in marked.js which is now incompatible with node version <=14. marked.js has started using optional chaining in their code thus breaking protobuf CLI compilation

npx pbjs -p <proto files> -t static-module -w default --force-message > index.js

protobufjs/cli/node_modules/marked/src/marked.js:158
const prevRenderer = extensions.renderers?.[ext.name];
                                                                           ^
  SyntaxError: Unexpected token '.'

Same with latest version 6.11.2 on node v12.18.3.
Error does not occur on node v14.8.0
