Fix npm dep deprecation issues

[frankfarzan]

We need to release new versions of:

• kpt-functions package (SDK)
• create-kpt-functions package (CLI)
• TS functions in the sdk repo (e.g. demo)
• TS functions in the catalog repo (e.g. kubeval)

It should address deprecation warnings such as this:

• TS SDK: Deprecation warning in CLI: crypto.createDecipher #564
• npm WARN deprecated request-promise@4.2.6: request-promise has been deprecated because it extends the now deprecated request package, see Request’s Past, Present and Future request/request#3142
• npm WARN deprecated request@2.88.2: request has been deprecated, see Request’s Past, Present and Future request/request#3142
• npm WARN deprecated har-validator@5.1.5: this library is no longer supported

We need to fix deprecation warning as next step.
