Cleanup

[nightwing]

• excluded esm-resolver.js from linter since it was printing error about using import in non-module, and was preventing embedding ace in cloud-editor
• converted line endings of some demo files to linux style
• updated the test to run with typescript latest and 3.7 to prevent introduction of types not compatible with old typescript (3.7 is the oldest version that works with ace atm)
• updated last case of timeout missed from https://github.com/ajaxorg/ace/pull/5726/files (this change is needed because typescript was generating different types depending on @types/nodjs package being installed in node_modules in some of parent directories)

Could you please add a summary of what changes you did? For example the change types/ace-lib.d.ts could have an impact on an integrator.

The changes itself look good to me.
