Have to commit the node_module folder

[rfennell]

Unfortunately, there is an issue with Handlebars that stops it from being used with ncc.

Until this is addressed the node-modules folder needs to be committed to the repo containing the production dependencies for use at runtime.

There error is

Processing template
Error: Invalid left-hand side in assignment
##[debug]Node Action run completed with exit code 1
##[debug]Finishing: Run /./

This has been logged with Handlebars as #375

A test was done using #82 but the problem still exists

Re tested with "@vercel/ncc": "^0.29.0" still has the same issue

I don't think there will be a solution to this without either replacing handlebars-helpers or forking and rebuilding, but I have raised an issue helpers/handlebars-helpers#375
