Add Typescript helloworld project sample

[THardy98]

What was changed

This change adds adds a helloworld sample project to Typescript.

There were a few changes in doing so, largely TS build fixes/improvements:

• added projects/tests/helloworld in workers/typescript, this is the actual helloworld sample
• add typescript as a language option for the project scenario (these are the changes in scenarios/project, along with a small change to inject clientReadyTimeout that tests use)
• simplify Dockerfile/entrypoint code for Python & TS for the project build path (just adds a project-name flag on the project build path now)
• added Typescript project coverage to test-omes in CI and project image CI
• updated TS workspace builds so the root workspace explicitly runs:
  1. root proto gen
  2. builds the project harness
  3. builds the root package

in that order.

This change in tandem with removing the harness prepare script, avoids a race where the project harness tries to build before the root workspace is finished generating protos.

• renamed src/omes.ts to main.ts, so project builds use the same main.ts entrypoint convention for builds

• Add ignore node_modules to go.mod so Go package discvoery does not recurse into npm dependency trees during go test ./... in test-omes

• the protogen.js change makes sure that both json-module.js and root.d.ts exist before skipping proto generation

• ignore node_modules in go.mod, allows for using go test ./... in CI, which fails when go walks the tree for ./...
