File paths in postgraphile handler is not transformed correctly when building for production. (Breaks production build)

[MarkLyck]

Describe the bug
When setting up the postgraphile handler using file paths like the below example. It does not translate the file paths when building the production output, and throws errors that modules are not found.

example:

sources:
  - name: crm
    handler:
      postgraphile:
        connectionString: MY_CONNECTION_STRING
        appendPlugins:
          - "@graphile-contrib/pg-simplify-inflector"
          - "./plugins/renameSubscriptionsPlugin"
        options: "./postGraphileOptions.json"
    transforms:
      - encapsulate:
          applyTo:
            query: true
            mutation: true
            subscription: true

This is supposed to load 2 modules, my ./postgraphileOptions.json file and my ./plugins/renameSubscriptionsPlugin file.

Both of these load without any issues when running mesh dev, and the schema also builds fine when running mesh build.

But when running mesh start after running mesh build I get the following error:

If I remove my custom plugin temporarily the error changes too:

This shows that any file paths set in the postgraphile handler does not seem to work when building for production.

Note: using local file paths works just fine when running mesh dev. It's only when running it in production it fails.

To Reproduce
Add any file path to a postgraphile handler and try to build and start for production.

Expected behavior
The file path should be translated correctly.

I tried to manually go edit the ouputted index.ts file to fix this, and got it working.

since the index.ts imports these as external modules and gives them a set name, I manually tried editing the these 2 lines and got it working:

appendPlugins: [
            "@graphile-contrib/pg-simplify-inflector",
            "./plugins/renameSubscriptionsPlugin",
          ],

should be:

appendPlugins: [
            "@graphile-contrib/pg-simplify-inflector",
            "plugins/renameSubscriptionsPlugin",
          ],

and

options: "./postGraphileOptions.json",

should be:

options: "postGraphileOptions.json",

and then the server will start with no issues when running mesh start
