Make config/paths.json exportable for ESM import

[colinrotherham]

This PR renames ./config/paths.json → ./config/paths.js as it's easier to import in ESM

Before

Parses import.meta.url due to no __dirname in ESM

import { dirname, resolve } from 'path'
import { fileURLToPath } from 'url'
import { readFile } from 'fs/promises'

const basePath = dirname(fileURLToPath(import.meta.url))
const configPaths = JSON.parse(await readFile(resolve(basePath, '../../paths.json')))

After (via import)

Plain CommonJS import

import configPaths from '../../paths.js'

Future (via import assertion from JSON)

Plain JSON import but needs --experimental-json-modules flag in Node.js 16

import configPaths from '../../paths.json' assert { type: 'json' }
